MALEIMIDE COPOLYMER COMPOSITION, ITS PREPARATION METHOD AND MOLDED PRODUCT THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a maleimide copolymer composition which has extremely low contents of unreacted monomer and other volatile components and shows extremely high heat resistance and a good hue, its industrial preparation method and a molded product thereof. SOLUTION: The maleimide copolymer composition is obtained by adding 0.01-4 pts.mass liquid polydiene to 100 pts.mass maleimide copolymer comprising 55-35 pts.mass aromatic vinyl monomer unit, 45-65 pts.mass maleimide monomer unit and 0-10 pts.mass monomer unit copolymerizable with these monomers. The maleimide copolymer composition has a maleimide monomer content of 0.1-300 ppm. COPYRIGHT: (C)2006,JPO&NCIPI
