摘要： Radiopaque polymers have a main chain and a plurality of amide groups which have bound to the amide nitrogen atom thereof an organohalide group that is pendant to the polymer main chain, the organo halide group including one or more iodine and/or bromine atoms thereon. The polymer may be a modified polyamide polymer, copolymer or block copolymer or a modified poly(meth)acrylamide or (meth)acrylamide copolymer or block copolymer. The polymers may be employed in medical devices and are useful for instance to track the movement of a catheter through the body or the inflation of a balloon at a site. The polymers may be made by coupling reactions performed on preexisting amide polymers.
