Abstract: An epoxy-acrylic graft copolymer useful as a paint film is prepared by the in-situ copolymerization of ethylenically unsaturated monomers including between 1% and 25% by weight of alkylated alkylol acrylamide monomer in the presence of at least 3% by weight of peroxide initiator in the absence of water. The unsaturated monomer chains are grafted by carbon-to-carbon grafts to the epoxy resin backbone. The resulting epoxy-acrylic graft copolymer is dispersed into water by adding amine, and is blended with from 1 to 40 parts by weight of aminoplast per 100 parts by weight of copolymer.

Abstract: A polymeric mixture comprising a graft copolymer of silicone resin is useful as a polymeric binder in paint coatings and particularly powder coatings. The polymeric mixtures are produced by copolymerizing ethylenically unsaturated monomers including glycidyl monomers in the presence of silicone resin to produce the graft silicone resins.

Abstract: Phenoxy terminated epoxy resins are grafted by carbon-carbon graft with ethylenic monomers, including alkylol acrylamide monomer, by in-situ polymerization to produce grafted epoxy-acrylic copolymers useful as binders in protective coatings. The cured paint films exhibit superior resistance to pine oil and limonene derivatives.

Abstract: A water-dispersed paint coating composition particularly useful for plastic substrates such as polystyrene foam comprises a polymeric binder of a functional acrylic copolymer and epoxy resin. Preferably, the epoxy resin is a coreaction product containing sorbitol. The polymers are water-dispersed and are adapted to cure and crosslink at ambient temperatures.

Abstract: A powder paint coating is based upon a thermosetting polymeric binder comprising a hydroxyl functional arcylic copolymer adapted to coreact upon heating with solid cyclic silicone resin.

Abstract: A fluorinated-silicone-acrylic terpolymer useful as a binder in powder coatings is prepared by step-wise synthesis. The process comprises reacting silicone resin with a fluorinated component to produce a fluorinated silicone resin followed by further reaction with hydroxylated acrylic prepolymer to form the flourinated-silicone-acrylic terpolymer.

Abstract: Provides new and improved water-reducible coating compositions and methods of making them. Three preferred processes are disclosed. These differ in the manner of incorporating and chemical nature of an extender polymer.Broadly, the process of the invention is one for forming an aqueous dispersion of a fluent resinous composition ofa. a mixture in an organic solvent of(i) an ionizable graft polymer of an epoxy resin and an addition polymerized resin, the addition polymerized resin being bonded to aliphatic backbone carbon atoms of the epoxy resin by carbon-to-carbon bonds, and(ii) an extender resin;b. an aqueous vehicle, andc. an ionizing agent;the ionization present from said combined components being sufficient to establish the components as a dispersion in the aqueous vehicle, and then addition polymerizing a quantity of addition polymerizable monomer, under addition polymerizing conditions, in said aqueous dispersion, the aqueous dispersion serving as a vehicle therefor.

Abstract: Sanitary coatings based on self-emulsifiable epoxy ester copolymers are produced by esterifying a solvent-soluble carboxyl polymer with an epoxy resin in an organic resin and in the presence of at least about 2% amine catalyst to provide a carboxyl-functional epoxy polymer which can be reacted with a base and dispersed into water.
