The invention is an inherently radiopaque, biocompatible, bioresorbable polymer, wherein said polymer comprises one or more recurring units of the Formula (I): (see formula I) wherein: X1 and X2 are each independently selected from the group consisting of Br and I; y1 and y2 are each independently zero or an integer in the range of 1 to 4, with the proviso that the sum of y1 and y2 is at least 1; R1 is (see formula II); R13 and R14 are each independently selected from the group consisting of -CH=CH-, -(CH2)C-, -(CHJ1)-, -CHJ2-CHJ3-, -CH=CH-(CHJ1)-, and -(CH2)c- (CHJ1)-; c is zero or an integer in the range of 1 to 8; J1 , J2 and J3 are each independently selected from the group consisting of H, Br, I, -NH-Q2 and -C(=Z8)-OQ3 ; Q1, Q2 and Q3 are each independently H or a non-crystallizable group comprising from 1 to 30 carbons; Z7 and Z8 are each independently O or S; A1 is selected from the group consisting of (see formula III), (see formula IV) and (see formula V) ; and R5 is selected from the group consisting of H, Cl - C30 alkyl, and Cl - C30 heteroalkyl. |
