Polymer concrete compositions of essentially anhydrous character comprising an inert, inorganic particulate or granular material, such as sand, crushed stone or rock, and mixtures thereof, mixed with a monomeric dicyclopentenyloxylalkyl acrylate or methacrylate or mixture thereof to form a paste or slurry suitable upon addition thereto of a polyvalent metal salt drier or siccative, preferably with an organic peroxide free radical initiator to be used to form (or to patch previously formed or laid) concrete floors and road pavements are disclosed.

Polymer concrete compositions, methods of application thereof, and

N-Substituted acryloyloxyethyl amines are useful both as radiation curable coating materials and as cure accelerators in coating formulations. The amines are prepared by one of several methods including transesterification of acrylate esters with an N-substituted hydroxyethylamine or acrylation of the N-substituted hydroxyethylamine.

Radiation curable compositions

The invention is concerned with novel autoxidizable compositions comprising an unsaturated acid ester of a glycol monodicyclopentenyl ether, a condensation or vinyl addition polymer, a siccative and a volatile stabilizer, which compositions are uniquely adapted to be formulated with high solids and practical viscosity ranges for coating and/or impregnating purposes.

Autoxidizable compositions

This invention is concerned with autoxidizable coating compositions which contain

Polyurethane coating compositions from dicyclopentenyl acrylate and/or

Polyurethane coating compositions containing unsaturated esters of

The present invention is concerned with film-forming polymer dispersions, especially in aqueous systems, such as aqueous solutions of polymers of monoethylenically unsaturated monomers as well as latices or dispersions in an aqueous medium of water-insoluble particles of polymers, such as those obtained by emulsion polymerization. It involves the addition to such aqueous polymer systems in order to improve hardness, blocking-resistance, print-resistance and film-formation to yield coherent films at room temperature or below, of a non-volatile, reactive monomer comprising a (meth)acrylic acid ester of a monohydroxy diolether of dicyclopentenyl alcohol to serve as an air-curing coalescent. The designation (meth)acrylic acid is intended to refer to either acrylic acid or methacrylic acid and also generically to both. Similarly, (meth)acrylate, if and when used in the specification and claims herein, is intended to generically refer to an 'acrylate' and a 'methacrylate'.

Water-based coating compositions

Disclosed herein is an improved process for preparing an addition product of the reaction of a polyhydric compound and dicyclopentadiene, using a molar ratio of polyhydric compound to dicyclopentadiene of from about 1:4 to about 2:1, in the presence of an acid catalyst wherein the product comprises a hydroxyhydrocarbyl dihydrodicyclopentadiene represented by the formula ##STR1## and wherein R is a divalent radical of 2 to 20 carbon atoms selected from the group consisting of saturated radicals, aromatic radicals and combinations thereof, the improvement comprising employing as the acid catalyst a crosslinked cation exchange resin having acid functionality.

Selective preparation of polyol monoethers of dicyclopentadiene

This invention is concerned with certain vinyl resin coating compositions in which the vinyl resin binder or film-forming component is normally dissolved in an organic solvent which is volatilized after application of the composition to the surface of substrates to be finished. The vinyl resin component is generally of high molecular weight and it is normally difficult to obtain a reasonable viscosity in the coating composition without excessive dilution with organic solvent and the necessity to apply a plurality of coats to obtain the desired protective thickness. The present invention has been found to alleviate or reduce this difficulty in the particular solution coating compositions with which it is concerned, namely thermoplastic vinyl or acrylic polymer solutions, polyvinyl acetals, and chlorinated polyisoprene containing about 64-65% chlorine. In the compositions of the present invention, the vinyl resin is dissolved in an organic liquid vehicle which consists essentially of a non-volatile reactive monomer including dicyclopentenyl acrylate or methacrylate or comprises a predominant proportion of such non-volatile reactive monomer. Also essential components are a siccative, that is, a polyvalent metal-containing complex or salt that catalyzes the oxidative curing of the mixture of the reactive monomer and the film-forming polymeric binder, and a fugitive agent, that is, a volatile oxime stabilizer, for inhibiting the action of the oxidation catalyst. The compositions may also contain pigments, rheology-control agents, pigment-dispersing agents and other components common in the coating art.

Vinyl resin coating compositions comprising dicyclopentenyl acrylate

The present invention is concerned with film-forming polymer dispersions, especially in aqueous systems, such as aqueous solutions of polymers of monoethylenically unsaturated monomers as well as latices or dispersions in an aqueous medium of water-insoluble particles of polymers, such as those obtained by emulsion polymerization. It involves the addition to such aqueous polymer systems in order to improve hardness, blocking-resistance and film-formation at room temperature or below, of a non-volatile, reactive monomer comprising dicyclopentenyl acrylacte or methacrylate to serve as an air-curing coalescent.

Curing photopolymerizable compositions containing n-substituted

An improved glossy, aqueous emulsion paint comprised of a mixture of a film-forming latex polymer and dispersed pigment is prepared by incorporating therein, as pigment dispersant, a water-soluble salt of a low molecular weight copolymer of hydroxyalkyl ester of acrylic or methacrylic acid and acrylic or methacrylic acid.

Dispersing paint pigments

This invention is concerned with coating and/or impregnating compositions comprising (a) A copolymer of 5 to 50% by weight of dicyclopentenyl acrylate or methacrylate with 50 to 95% by weight of at least one other monoethylenically unsaturated comonomer. (b) An essentially non-volatile reactive comonomer consisting of dicyclopentenyl acrylate or methacrylate or a mixture thereof, or comprising a mixture of at least 50% by weight of one or both of these monomers with up to 50% by weight of at least one other reactive monomer, such as a (C.sub.10 -C.sub.20)alkyl acrylate or methacrylate, a (C.sub.10 -C.sub.20)alkenyl acrylate or methacrylate, a di(C.sub.4 -C.sub.20)-alkyl fumarate, maleate, or itaconate, or a polyethylenically unsaturated monomer, such as a polyol polymethacrylate, e.g. glycol dimethacrylate, or the analogous diacrylate, or mixtures of two or more such monomers. (c) A polyvalent metal-containing complex or salt that catalyzes the oxidative curing of a) and b), such as cobalt naphthenate, and (d) A volatile oxime stabilizer. Such compositions are characterized by the fact that they can have exceptionally high solids content and rapid cure by air-drying to exceptional properties of hardness and resistance to solvents even without baking.

Air-dry curable compositions comprising dicyclopentenyl (meth) acrylate

The invention is concerned with novel unsaturated compounds having extremely low volatility having a single monoethylenically unsaturated group of the formula H.sub.2 C = C < whereby they are capable of polymerization to produce linear homopolymers and copolymers with copolymerizable monomers containing such a group, and having autoxidizable characteristics by virtue of a different type of unsaturated group. These new compounds are useful for the production of polymers, alone or in admixture with other polymers or monomers to modify the characteristics of the components of the mixture. They are useful in coating or impregnating compositions and/or in the molding, casting, or otherwise forming of shaped articles.

Unsaturated esters of glycol monodicyclopentenyl ethers

This invention is concerned with coating compositions comprising an unsaturated polyol/polycarboxylic acid alkyd or polyester condensate resin (including drying oil-modified alkyd), the polycarboxylic acid or anhydride precursor(s) of which alkyd may be aromatic, aliphatic, or both. In one preferred embodiment Type A, the polyacid is predominantly or exclusively aliphatic and in another Type B, it is predominantly or exclusively aromatic in character. The alkyd or polyester is carried (dissolved) predominantly or exclusively in a substantially non-volatile reactive liquid consisting essentially of a) dicyclopentenyl acrylate or methacrylate or mixtures thereof or of b) a mixture of such (meth)acrylate with one or more alkyl or alkenyl esters of acrylic or methacrylic acid in which the alkyl and/or alkenyl group contains 10 to 20 carbon atoms. The compositions also contain a polyvalent metal-containing drier or siccative; optionally a volatile agent for inhibiting the action of the drier, i.e., a fugitive stabilizer; they may also contain pigments, rheology control agents, pigment-dispersing agents, and other components.
