    摘要: R=C.sub.1 -C.sub.25 alkyl, cycloalkyl, ##STR2## or halo-lower-alkyl, each of which may be optionally substituted with halo, fluoro-lower-alkyl, aryl, lower-alkoxy, hydroxy, carboxy, lower-alkoxy carbonyl or lower-alkoxy-carbonyloxy, (CR.sub.1 R.sub.2).sub.p --(CR.sub.3 =CR.sub.4).sub.m Q ,or (CR.sub.1 R.sub.2).sub.p --C.tbd.C--Q;R.sub.1, R.sub.2 and R.sub.3 and R.sub.4 are independently H, or lower-alkyl, optionally substituted with halo;x is 1-4;n is 1-4;m is 1-15;p is 1-20; andQ is H, lower-alkyl, lower-alkenyl, lower-alkynyl, lower-alkylene, aryl, or aryl-lower alkylThese compounds are combined in a polymer for use as an X-ray contrast agent.
