Hot melt adhesive compositions, particularly biodegradable hot melt adhesives are prepared from 10 to 90% by weight of a thermoplastic methylol polyester prepared from the reaction of at least one dicarboxylic acid with a diglycidyl ether, a diglycidyl ester or a combination thereof; 0 to 90% by weight of a compatible tackifier; 0 to 80% by weight of a compatible plasticizer; 0 to 50% by weight of a compatible wax diluent and 0 to 3% by weight of a stabilizer.

Hot melt adhesives based on hydroxy-functional polyesters

A process for preparing methyl .alpha.-cyanoacrylate in which methyl cyanoacetate is reacted with formaldehyde to form a polymer, which is subsequently depolymerized to the monomeric product, comprises using an ester of poly(ethylene glycol) as the solvent for the polymerization and depolymerization reactions.

In a two-part adhesive composition wherein one-part comprises a polymerizable acrylic monomer and an organoboron amine complex and the second-part contains an organic acid destabilizer and optional acrylic polymer, the improvement wherein a transparent or clear bond is provided in the cured adhesive composition by having about 45% or more by weight of the total acrylic monomer in the composition comprising selected phenyl containing acrylic compounds.

Transparent two-part acrylic adhesive composition and the method of use

This invention presents water-resistant, formaldehyde-free starch-based corugating adhesives. The adhesives are alkaline-curing and contain 0.1-7% (by wt.) of a crosslinking agent which is a condensate of an epihalohydrin and an amine, a polyamine, or ammonia.

Water resistant formaldehyde-free corrugating adhesive compositions

This invention provides novel adducts of cyclic ethylene urea which are useful as permanent press agents. These adducts include acid, polyacid, ester, and multiester derivatives of cyclic ethylene urea and can be produced by the reaction of the cyclic ethylene urea with glyoxylic acid and glyoxylic acid derivatives, specifically ester acetals of glyoxylic acid. Such materials impart a high degree of permanent press properties to cellulose and cellulose/polymer blend fabrics.

Ethylene urea compositions useful as permanent press promoting chemicals

Polysaccharide graft copolymers are prepared by a water-in-oil emulsion polymerization process in which the polysaccharide and water-soluble monomer are emulsified in an oil phase containing emulsifying agents and polymerized therein. The resultant emulsion polymers are in stable form and may be used directly, for example, as adhesives for prepasted wallpaper, or may be inverted into aqueous systems and used for their thickening or flocculating properties.

Inverse emulsions

Novel gelling agents are prepared by reacting diphenyldiisocyanates with sulfur trioxide in a molar concentration of about 1:2. When the sulfonated diphenyldiisocyanate is added to water in concentrations above 2%, a gel is produced which is stable under acidic conditions at pH levels of about 4 or less.

Novel gelling composition

Novel acrylic adhesive compositions are prepared comprising an acrylic or substituted acrylic monomer and a normal poyimide or polyisomide bis-acetylene additive.

High temperature stable acrylic adhesive compositions employing aromatic

A hot-melt adhesive especially useful in the construction of disposable diapers contains a vinyl polymer of 40-90% by weight of a C.sub.1 -C.sub.12 alkyl acrylate and 10-60% by weight of an alpha-olefin of C.sub.20 -C.sub.40, wherein the alkyl acrylate may be partially replaced with vinyl acetate or with a C.sub.6 -C.sub.12 olefin or with mixtures thereof, provided that the polymer contain at least 10% by weight of the alkyl acrylate. The adhesive may also contain a tackifying resin, a wax, an oil or a stabilizer depending on the specific end-use desired. In a preferred embodiment the polymer contains 20-45% by weight of the alpha-olefin.

Maleated aminophenoxysiloxanes are prepared by reacting diaminodiphenoxysiloxanes with maleic anhydride. In addition, the resultant maleamic acid derivatives may be cyclized yielding isomaleimide or maleimide siloxane derivatives.

Maleated siloxane derivatives

Novel anaerobic curing compositions prepared containing polymerizable (meth)acrylate monomers, free radical initiators and, as a polymerizable activators therefor, monomeric disulfonimides.

Novel curing compositions are prepared comprising an acrylic or substituted acrylic monomer and a normal polyimide or polyisoimide bis-acetylene additive.

High temperature stable adhesive compositions employing aromatic

The invention provides disulfonimide compounds of the general formula ##STR1## wherein X is bromine, chlorine or iodine; R is hydrogen or methyl; and R' is alkyl, aryl or substituted aryl. The compounds are useful as activators for anaerobic adhesive compositions and also as intermediates in the preparation of monomers of the general formula ##STR2## wherein R and R' are as defined above. The monomers are polymerizable to form homo- and copolymers useful in the photographic industry as well as in formulating anaerobic adhesive compositions.
