Abstract
1,200,531. Graft polymer-other polymer compositions. PRODUITS CHIMIQUES PECHINEY-SAINT-GOBAIN. 26 Feb., 1968 [27 Feb., 1967], No, 9249/68. Heading C3G. A composition having an apparent density of 0À3 to 0À65 g./c.c. of a graft polymer as defined below and a non-agglomerating polymer is obtained by coagulating a latex of the graft polymer and mixing the coagulate with a latex of the non-agglomerating polymer, under agitation, followed by separating, washing and drying the product. The latter polymer is defined as having a second order transition temperature of at least 0‹ C. and an elasticity modulus of at least 1000 kg./cm.<SP>2</SP>. A wide variety of such polymers derived from ethylenically unsaturated monomers is described. The graft polymer is a halogen containing polymer, suitably a vinyl chloride polymer, on to which a conjugated diene has been grafted. The usual techniques for coagulation such as adding salt or acid solutions may be employed. The examples relate to the use of, as graft polymers, butadiene, styrene and acrylonitrile, butadiene and methyl methacrylate, butadiene, ethyl acrylate, styrene and divinyl benzene and butadiene, acrylonitrile and, optionally, divinyl benzene on polyvinyl chloride and, as the non-agglomerating polymer, polyvinyl chloride, polymethylmethacrylate, polystyrene, a vinyl acetate-vinyl chloride copolymer and a styrene-acrylonitrile-methyl styrene terpolymer.
