Claim:
A compound, comprising a polymeric backbone, cyclic olefinic pendent groups and linking groups linking the olefinic pendent groups to the polymeric backbone, and comprising the formula (II) as follows: wherein P+T+Q is 100 mol % of the compound; P, T, and Q are each greater than 0 mol % of the compound; Z is selected from the group consisting of an aryl group; —(C═O)OR 1 ; —O(C═O)R 1 ; and an alkyl aryl group: where R 4 is selected from the group consisting of −CH 3 , ethyl, and hydrogen; R 1 is selected from the group consisting of hydrogen, methyl, ethyl, —C 3 H 7 and —C 4 H 9 ; R 2 and R 3 are selected from the group consisting of hydrogen and methyl; X is selected from the group consisting of —O—, —NH—, —(C═O)O—, —(C═O)NH—, —(C═O)S—, —O(C═O)— and —(CHR) L —; L is an integer in the range from 1 to 6; Y is —(CHR) n —, where n is an integer in the range from 0 to 12, R being selected from the group consisting of hydrogen, methyl and ethyl; where q 1 , q 2 , q 3 , q 4 , and r are selected from the group consisting of hydrogen, methyl, and ethyl; and where m is —(CH 2 ) n — and where n is an integer in the range from 0 to 4; and wherein when r is hydrogen, at least one of q 1 , q 2 , q 3 and q 4 is hydrogen.
