    摘要: There is provided a process for producing a styrenic graft copolymer which comprises coplymerizing a styrenic monomer and a styrenic monomer having a hydrocarbon radical with an unsaturated bond in the presence of a catalyst comprising as primary ingredient (A) a transition metal compound and (B) a contact product of an organoaluminum compound and a condensation agent or (C) a compound which produces an ionic complex by reacting with the above-mentioned transition metal compound and subsequently graft polymerizing an ethylenically unsaturated monomer onto the resultant styrenic copolymer.The above-described styrenic graft copolymer is greatly improved in terms of compatibility, adhesivity, coatability and wettability while preserving heat resistance and chemical resistance thereof, and thus effective as a variety of constructional materials and compatibilizing agents. Furthermore, the composition or multi-layer material comprising the above-mentioned styrenic graft copolymer is widely utilized in a variety of application field including film, sheet, especially stampable sheet, container, packaging material, automobile parts, electrical and electronic parts, etc.
