Patent ID: 7939611

Claim:
A polymer comprising: a main chain; a plurality of crystallizable side chains; and a plurality of heavy atoms attached to the polymer, the heavy atoms being present in an amount that is effective to render the polymer radiopaque, wherein the polymer comprises a recurring unit of the formula (I): wherein: X 1 and X 2 are each independently selected from the group consisting of Br and I; y 1 and y 2 are each independently zero or an integer in the range of 1 to 4; A 1 is selected from the group consisting of R 3 is selected from the group consisting of C 1 -C 30 alkyl, C 1 -C 30 heteroalkyl, C 5 -C 30 aryl, C 6 -C 30 alkylaryl, and C 2 -C 30 heteroaryl; R 4 is selected from the group consisting of H, C 1 -C 30 alkyl, and C 1 -C 30 heteroalkyl; R 1 is Z is O or S; R 5 and R 6 are each independently selected from the group consisting of —CH═CH—, —CHJ 1 -CHJ 2 -, and —(CH 2 ) a —; a is zero or an integer in the range of 1 to 8; J 1 and J 2 are each independently selected from the group consisting of Br and I; and Q is a crystallizable group comprising from about 6 to about 30 carbon atoms after the recitation “radiopaque”.
