| titleOfInvention | Process for producing maleimide copolymer and thermoplastic resin composition comprising the copolymer |
| abstract | A process for producing a maleimide copolymer by emulsion polymerization of an aromatic vinyl monomer, a vinyl cyanide monomer, and a maleimide monomer in a specific mixture ratio, which comprises feeding an aromatic vinyl monomer in an amount more than a specified amount and, if necessary, a vinyl cyanide in an amount less than a specified amount before initiation of the polymerization, and adding continuously or by portions thereto, after initiation of the polymerization, the rest of the monomer mixture including the whole amount of a maleimide monomer, while keeping the pH of the aqueous phase of the polymerization system at 3 to 9 upon initiation of polymerization and using a redox catalyst comprising an oil-soluble organic peroxide. This process provides a maleimide copolymer having good heat resistance and heat decomposition resistance in a high yield. A thermoplastic resin composition prepared by compounding the maleimide copolymer with a rubber reinforced resin obtained by grafting a vinyl cyanide monomer to a specified elastomer in a specified proportion, which may optionally be further blended with a thermoplastic resin hard at room temperature, is also disclosed. The resin composition has excellent heat resistance, heat decomposition resistance, and impact resistance. |
