Abstract: A polyfunctional reaction product having functional phenolic OH groups is made available by reacting a phenol and an alkoxylated amino-aldehyde condensation product in the presence of a solvent and of an acid catalyst. This method makes it possible to prepare a polyfunctional phenolic reaction product which is soluble in organic solvents at a low ratio of phenolic OH groups to alkoxy groups without gelling. The reaction product is particularly useful as a curing agent for epoxy resins.

Abstract: The epoxy resin composition is comprised of an epoxy resin, a solvent and a hardener which is the reaction product of a hexa-alkyl ether of a methylol melamine having the general formula (I), wherein each R, independently, is an alkyl radical having from 1 to 4 carbon atoms with a polyhydric phenol and, optionally, a monohydric phenol, with the phenol compound(s) having been employed in an amount to provide a ratio of at least one reactive phenolic hydroxy group for each alkoxy group.

Abstract: The formation of non-aqueous polymeric dispersions, solutions, hydrosols and collodial suspensions by polymerizing vinyl monomers (A) in a hydrocarbon medium containing dissolved therein a stabilizing component (B) comprising an acrylic polymer previously formed from acrylic monomers (E). The invention comprises use, in (B), of minor proportions of (2-(1-aziridinyl)-ethyl- methacrylate to provide, by reason of its high reactivity, higher molecular weight backbones (B) and simultaneously by reason of its high functionality, to provide active sites for grafting side chains onto backbone (B). Furthermore, the reactivity thereof can make the final product self-cross-linking. The above system produces a dispersion of a vinyl polymer (C) formed from the polymerized vinyl monomers (A) in the hydrocarbon medium wherein a modified stabilizer (D) is formed either in situ from a precursor or in a preliminary separate step by grafting a portion of the vinyl monomers (A) onto the soluble polymeric stabilizer backbone (B).

Abstract: Aqueous dispersions of interpolymers containing a base monomer such as styrene or methyl methacrylate, an alkylene glycol monomer such as (tripropylene glycol methyl ether) acrylate and a,b-ethylenically unsaturated carboxylic acid such as acrylic acids are useful as low viscosity coating compositions which can be cured to water resistant coatings.

Abstract: A dielectric coating for use on electroconductive papers consisting essentially of an interpolymer containing about 80 parts by weight of vinylidene chloride and at least about 1 part by weight of a vinyl acid, said interpolymer being obtained by polymerization in non-aqueous dispersion (NAD) comprising a strongly hydrogen bonded dispersing media containing from about 0.1 to 20 percent of a preformed dispersion stabilizer comprising the reaction product of (A) tripropylene glycol methylether acrylate and (B) at least one reactive comonomer capable of forming a side chain on said stabilizer which side chain is dispersible in said vinylidene chloride interpolymer and wherein the mass ratio of (A) to (B) is from about 99:1 to 80:20.
