Title: Improvements in plasticized compositions and process for preparing the same
IPC: C08G8/00
Filed: 1945-04-11
Abstract: A homogenous plasticised composition comprises an elastomer compounded with a phenolic resin without the inclusion of an organic solvent, said elastomer being a copolymer of a conjugated diolefin with an acrylonitrile, the acrylonitrile content of the copolymer being from 10 to 75 per cent and the amount of said phenolic resin being from 10 to 900 per cent based on the weight of the elastomer. The copolymer may be obtained from a diene of the general formula <FORM:0608947/IV(a)/1> in which R is hydrogen or methyl and R1 is hydrogen, methyl, or chlorine; such as butadiene, isoprene, 1-methyl-1,3-butadiene, 2,3-dimethyl-1,3-butadiene, 2-chloro-1,3-butadiene, and an acrylonitrile of the formula <FORM:0608947/IV(a)/2> in which R11 is hydrogen, methyl, ethy, propyl or chlorine; such as acrylonitrile, methacrylonitrile, ethyl acrylonitrile, propyl acrylonitrile and chloroacrylonitrile.  The phenolic resins may be compounds of phenol, o-, m- and p-cresols, xylenols, dihydroxybenzenes, polynuclear phenols, e.g. naphthol, alkylated, aralkylated, carboxylated and alkylolated derivatives of phenol such as o-ethyl phenol, carvacrol and salicylic acid with aldehydes such as formaldehyde, acetaldehyde, propionaldehyde and benzaldehyde.  Additional substances which may be included are polyvinyl chloride, polyvinyl acetate, and vinyl chloride-vinyl acetate copolymers, urea-formaldehyde, melamine-formaldehyde, sulphur, benzothiazyl disulphide.  The compositions may be used as an adhesive for fabrics, wood, paper, rubber, plastics and metal, as an artificial leather, for coating fabrics, and for making films.ALSO:A homogenous plasticized composition comprises an elastomer compounded with a phenolic resin without the inclusion of an organic solvent, said elastomer being a copolymer of a conjugated diolefin with an acrolynitrile, the acrylonitrile content of the copolymer being from 10 to 75 per cent and the amount of said phenolic resin being from 10 to 900 per cent based on the weight of the elastomer.
