Title:
ETHYLENE/POLAR GROUP-CONTAINING CYCLIC OLEFIN COPOLYMER
Document Type and Number:
Japanese Patent JP3719308
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain a random addition copolymer of a cyclic olefin having a polar group such as an ester group or an acid anhydride group with ethylene.
SOLUTION: This copolymer has (a) a structural unit derived from ethylene and (b) a structural unit derived from a polar group-containing cyclic olefin expressed by the formula [A and B are each a hydrogen atom or a 1-10C hydrocarbon group; either of X and Y is an ester group expressed by (CH2)nCOOR {R is a 1-20C hydrocarbon group and (n) is an integer of 0-10} and the other is a hydrogen atom, a 1-10C hydrocarbon group or an ester group expressed by (CH2)nCOOR {R and (n) are respectively same as the above}, or X and Y bond with each other to form a bifunctional group expressed by (CH2)n-CO-O- CO-(CH2)n {(n) is same as the above}; (m) is 0 or 1]. The copolymer has 1,000-100,000 number-average molecular weight calculated as polystyrene and a content of the structural unit derived from the polar group-containing cyclic olefin in the copolymer of 1-99 mol.%.
