1,3-diketoamide functional polymers and compositions employing the same

This invention provides stable waterborne polymer compositions, which are stabilized against gelling, comprising a stable waterborne polymer composition having a Tg of greater than about 0&deg; C. and comprising an acetoacetoxy-type functional polymer, a poly(alkylenimine), and a nonionic surfactant having a hydrophilic-lipophilic balance (HLB) of at least about 17.5. The waterborne polymer compositions of the invention are particularly useful in a variety of adhesive formulations such as pressure sensitive adhesives, laminating adhesives, and the like. Methods of making stable waterborne polymer compositions are also disclosed.

Stable waterborne polymer compositions containing poly(alkylenimines)

This invention provides waterborne polymer compositions stabilized against gelling due to the addition of a poly(alkylenimine) by post addition of certain anionic surfactants. The waterborne polymer compositions of the invention are useful in a variety of coating formulations such as, for example, paints, inks, sealants, textile back coatings, adhesives and the like. Methods of making stable waterborne polymer compositions are also disclosed.

Stable waterborne polymer compositions containing poly(alkyleneimines)

This invention provides waterborne polymer compositions stabilized against gelling due to the addition of a poly(alkylenimine) by addition of nonionic surfactants having a hydrophilic-lipophilic balance (HLB) of at least about 17.5. The waterborne polymer compositions of the invention are useful in a variety of coating formulations such as, for example, paints, inks, sealants, textile backcoatings, adhesives and the like. Methods of making stable waterborne polymer compositions are also disclosed.

This invention provides low foam waterborne polymer compositions stabilized against gelling due to the addition of a poly(alkylenimine) by addition of surfactants. Preferably, the surfactants are nonionic surfactants having a hydrophilic-lipophilic balance (HLB) of at least about 17.5. Polymerization in the presence of phosphate surfactants has been found to yield low foam polymers. These stable low foam polymer compositions are useful in a variety of coating formulations such as, for example, paints, inks, sealants, textile backcoatings, adhesives and the like. Methods of making stable low foam polymer are also disclosed.

Stable low foam waterborne polymer compositions containing

The present invention is directed to polymer compositions containing a vinyl polymer component (A), formed by polymerization of .alpha.,.beta.-ethylenically unsaturated monomers, one which contains at least one hydroxyl group and one which contains no hydroxyl groups; a crosslinker component (B); an additive component (C); and a solvent component (D). The composition is useful for backcoating woven substrates and as a binder composition for non-woven substrates.

Self-crosslinking aqueous dispersions

Disclosed are polymer blends of polyesters or polyesteramides and a polymer containing an acrylamide sulfonate monomer. The blends are preferably prepared by polymerizing monomers in the presence of the polyester or polyesteramide. The blends impart superior freeze-thaw stability to aqueous compositions such as inks.

Polymer blends for aqueous dispersions having improved freeze-thaw

Disclosed is a novel ink reservoir containing a polyester fiber, such as a poly(ethylene terephthalate) fiber, having at least one continuous groove. The surface of the groove of the fiber is preferably rougher than the surface outside the groove. The ink reservoirs are useful for use with aqueous inks and have improved ink transport properties.

Disclosed is an improved process for the preparation of alkyl 3-alkoxypropionates by the reaction of a dialkoxymethane with a diketene in the presence of methanedisulfonic acid, methanetrisulfonic acid or mixture thereof.

Process for the preparation of alkyl 3-alkoxypropionates

Disclosed is an improved process for the preparation of alkyl 3-alkoxypropionates containing at least seven carbon atoms by the reaction of dialkoxymethane containing five or more carbon atoms with a ketene in the presence of a catalytic amount of the reaction product of an alkylcarboxylic acid anhydride and concentrated or fuming sulfuric acid.

A process for purifying diethoxymethane from a mixture containing ethanol and, optionally, water. The process involves the addition of an amount of water, DEM, or an appropriate mixture of any two or three of water, DEM and ethanol that is effective in moving the mixture into the two liquid phase region on an equilibrium tie-line which crosses the critical distillation boundary without the need for additional azeotrope-forming agents such as cyclohexane.

Process for the purification of diethoxymethane from a mixture with

Disclosed is a novel process for the separation of meta and para isomers of the sodium salt of bromophenol. Derivatives of the sodium salt of metabromophenol are useful chemical intermediates.

Process for the separation of meta and para isomers of the sodium salt

Disclosed is a process for the preparation of thiophenes having the formula ##STR1## by contacting a compound having the formula ##STR2## with certain amine bases. Other amine bases can be employed when a two-phase reaction system is used.
