23 Jul Iodine-containing polycarbonate/polyester material for X-ray development and preparation method and application thereof
Abstract
The invention belongs to the field of biomedical polymer materials, and particularly relates to an iodine-containing polycarbonate/polyester polymer for X-ray development and a preparation method andapplication thereof. The iodine-containing polycarbonate/polyester polymer disclosed by the invention has excellent X-ray radiopacity or property of weakening X-rays. Under the existence of a catalyst, with a small-molecule hydroxyl compound as an initiator, through the ring-opening homopolymerization of an iodine-containing carbonate monomer or the ring-opening copolymerization of the iodine-containing carbonate monomer and other lactone, lactide and/or carbonate monomers, the iodine-containing polycarbonate/polyester material is obtained. The iodine-containing polycarbonate/polyester polymercan be applied in fields such as visualized embolization materials, anti-counterfeit labels, contrast media, antibacterial materials, prevention or treatment of iodine deficiency disorders, flame-retardant materials, tissue engineering and drug delivery systems.
