ABSTRACT:
High impact and weather resistant graft copolymers are produced by a two-stage process comprising (I) carrying out bulk or suspension polymerization of a mixture obtained by impregnating a substantially non-polar rubber-like polymer having iodine value of 2 to 40 with a mixture of an aromatic vinyl compound and a polar vinyl compound in the presence of a polymerization initiator to yield a graft copolymer, and (II) subjecting a mixture obtained by dispersing with partly dissolving (or impregnating) the graft copolymer in (or with) a mixture of an aromatic vinyl compound and a polar vinyl compound to bulk, suspension or bulk-suspension polymerization in the presence of a polymerization initiator.
