Abstract: This paper reviews the preparation of biomedical polymer materials via living / controlled polymerization，including living free radical polymerization，living anionic polymerization，living cationic polymerization，and living coordination polymerization. They are used as non-viral gene delivery system，nanocarrier，medical carrier，artificial lung membrane，and so on. The trend of biomedical polymer materials in the future is also prospected.

摘要： 综述了活性/可控聚合方法（活性自由基聚合、活性阴离子聚合、活性阳离子聚合以及活性配位聚合）制备生物医用高分子材料的研究进展，制备的医用高分子材料可用于非病毒转基因载体、药物控释载体、纳米材料、人工肺膜材料等方面。展望了生物医用高分子材料的发展趋势。
