Abstract

Polymer dispersions are made by polymerizing an addition polymerizable monomer charge in a substantially anhydrous liquid hydrocarbon medium in which the resulting polymer is insoluble, the dispersion being stabilized by a polymeric dispersing agent which is a graft copolymer having a first component preferentially soluble in the hydrocarbon medium and, grafted thereon a second component preferentially soluble in the dispersed polymer, the first component being an oxidative degradation product of rubber and which has a viscosity of 1 to 2000 c.p.s. at 25 DEG C. in a 10 wt. per cent solution in mineral spirits. Preferred rubbers are crepe rubber, an isobutylene-isoprene copolymer, polyisoprene, and an ethylene/propylene copolymer. The rubbers may be oxidatively degraded by treatment with ozone, or by heat-treatment in air in the presence of an organic peroxide. The methods of polymerization are of the type described in Specification 934,038. The examples describe the preparation of dispersions from monomer charges consisting of: (1-5) ethyl acrylate, methyl methacrylate and, optionally, acrylic acid, (6) ethyl acrylate, methyl methacrylate, methacrylic acid and vinyl toluene, (7) ethyl acrylate, methyl methacrylate and 2-ethylhexyl acrylate, (8) ethyl acrylate, methyl methacrylate and methacrylamide, (9) butyl acrylate and acrylonitrile, (10) vinyl chloride, and (11) vinyl acetate. The resulting dispersions are used for coating various substrates. Specification 893,429 also is referred to.ALSO:Surfaces of metal, glass and wood are coated by applying thereto polymer dispersions made by polymerizing monomer in a liquid hydrocarbon in which the resulting polymer is insoluble, and which contains an oxidative degradation product of rubber as the precursor of a dispersing agent formed by graft polymerization with the monomer (see Division C3). The examples describe coating: (1-4) steel surfaces with dispersions of copolymers of methyl methacrylate, ethyl acrylate and, optionally, acrylic acid, (5) glass with a dispersion of a copolymer of methyl methacrylate, ethyl acrylate and acrylic acid, (6) steel with a dispersion of a copolymer of methyl methacrylate, ethyl acrylate, methacrylic acid and vinyl toluene, (7) steel and aluminium with a dispersion of a copolymer of methyl methacrylate, ethyl acrylate and 2-ethylhexyl acrylate, (8) glass, metal and wood with a dispersion of a copolymer of methyl methacrylate, ethyl acrylate and methacrylamide, and (9) copper wire with a dispersion of a copolymer of butyl acrylate and acrylonitrile. Specifications 893,429 and 934,038 are referred to.
