Patent number: 6437051Abstract: The present invention provides a graft copolymer of a syndiotactic styrene/para-alkylstyrene copolymer, having the formula of wherein R1 and R2 are independently selected from the group consisting of hydrogen, alkyl, and primary and secondary haloalkyl; X is a functional group selected from a group containing halogen, oxygen, sulfur, silicon, nitrogen, carbon, phosphorus, and mixtures thereof; Y is an atactic polymer moiety; a ranges from 10 to 30000; b ranges from 0 to 30000; c ranges from 0 to 30000; and d ranges from 1 to 30000. The compatibility of the graft copolymer of syndiotactic styrene/para-alkylstyrene copolymer of the present invention with other polymers is improved over a syndiotactic styrene polymer. Also, the graft copolymer of the present invention can serve as a compatibilizer for a polymer blend.Type: GrantFiled: December 29, 2000Date of Patent: August 20, 2002Assignee: Industrial Technology Research InstituteInventors: Chi-Lan Li, Jing-Cherng Tsai, Joung-Yei Chen, Wee-Pin Chao, Bor-Ping Wang, In-Mau Chen, Huai-Mei Chou
