Abstract

1305779 Graft polymerization process FOSTER GRANT CO Inc 13 Aug 1970 [15 Aug 1969] 39152/70 Heading C3G An ABS polymer is prepared by (a) bulk polymerizing a mixture containing at least one vinyl aromatic monomer, at least one monomer selected from acrylonitrile and methacrylonitrile and at least one rubber; (b) adding 0À20 to 1À0%, based on the weight of monomers and rubber, of unsaturated alpha-methylstyrene dimers to the polymerization mixture, at least 0À125% of which dimers is added after 2 to 15% by weight of the monomers has been converted to polymer and the remainder, if any, is subsequently added in one or more increments; and (c) continuing bulk polymerization until substantially all of the monomer has been polymerized, or continuing bulk polymerization until 20 to 50% of the monomers has been polymerized and completing the polymerization in aqueous suspension. In the example, the dimers are added in three increments during bulk prepolymerization of a mixture of styrene, acrylonitrile, butadiene-styrene rubber and polybutadiene and polymerization is completed in suspension.
