shapes as medical devices providing the bulk material from which the end product or device is formed the polymers may also be used as a polymeric coating or a drug release barrier for device drug combination products or to simply enhance the radiopacity of the device for which the material is coated upon or incorporated within the reaction between a hydroxyl group containing compound and an iodine containing aromatic compound may be processed for synthesizing an iodine containing contrast agent this invention expands the concept further and used a protected bi tri or tetra hydroxyl containing compounds to make a functional initiator upon deprotection of fmoc 9 fluorenylmethoxycarbonyl as shown in fig9 the initiator can be used to initiate a ring opening reaction of cyclic lactones such as lactide glycolide to form an iodine containing polymer other commonly used protecting groups for amine and hydroxyl groups other than fmoc such as boc z ddz tert butyl cbz may be expressly used to substitute for fmoc as a suitable protecting group in the reaction the ring opening reaction is well researched and used in production of other biocompatible materials such as resorbable sutures the final end capping step as shown in fig1 and 13 is a variation of regular end capping of a methanol to impart more iodine content of the bioabsorbable polymer in accordance with the present invention multiple iodine molecules are built into a single initiator of a ring opening reaction a bioabsorbable polymer contains a large number of iodine atoms without sacrificing the mechanical properties of the bulk materials for example such a bioabsorbable polymer may contain twice the number of iodine atoms by end capping with a derivative of the iodine containing functional initiator such iodine containing bioabsorbable.
