Patent number: 4242243Abstract: A high solids coating composition that dries rapidly to a tack-free finish and cures under ambient temperature conditions to a durable finish useful for metals, plastics, wood, fiberglass reinforced plastics; the coating composition is used as a finish for automobiles, trucks, trailers, tractors, appliances and airplanes and also used to refinish automobiles and trucks; the film forming polymer of the coating composition has a backbone of polymerized monomers of an alkyl methacrylate such as methyl methacrylate or styrene, an alkyl acrylate and hydroxyl containing monomers such as a hydroxy alkyl acrylate or a hydroxy alkyl methacrylate and has attached thereto pendant drying oil fatty acid groups to provide the composition with ambient curing characteristics; wherein these drying oil fatty acid groups are attached by a reaction of the carboxyl group of the drying oil fatty acid and pendant hydroxyl group of the polymer backbone.Type: GrantFiled: July 18, 1979Date of Patent: December 30, 1980Assignee: E. I. Du Pont De Nemours and CompanyInventors: Joseph A. Antonelli, Renee J. Kelly, Joseph E. McLaughlin

Patent number: 4234468Abstract: The present invention relates to a special copolymer solution consisting of acrylic resin containing 70 to 90% by weight of copolymer solids and 10 to 30% by weight of solvent. The invention also relates to a process for the manufacture of the copolymers which are present in the copolymer solution; additionally, the invention relates to the use of the copolymer solution for the manufacture of coating compositions for lacquer systems of low solvent content which contain polyisocyanates and which contain the copolymer manufactured according to the invention as a resin component which carries hydroxyl groups.Type: GrantFiled: February 21, 1979Date of Patent: November 18, 1980Assignee: Hoechst AktiengesellschaftInventor: Horst Dalibor

Patent number: 4225664Abstract: A mixture of poly(2,3-dichloro-1-propyl acrylate) and poly(glycidyl methacrylate-co-ethyl acrylate), with the latter forming between 1 percent and 20 percent by weight, of the total polymer mixture, has been found to form an x-ray resist having adhesive and resolving properties superior to those of poly(2,3-dichloro-1-propyl acrylate) which is a good x-ray resist material. Superior properties of the mixture are attributed to the fact that the two polymers form a compatible polymer mixture which is a relatively rare and unpredictable event in polymer chemistry.Type: GrantFiled: February 22, 1979Date of Patent: September 30, 1980Assignee: Bell Telephone Laboratories, IncorporatedInventors: Joseph M. Moran, Gary N. Taylor
