【摘要】 聚乙烯醇(PVA)是一种常用的生物相容性材料,但熔点高、加工性能差等,对聚乙烯醇进行改性已成为当前的研究热点。综述了近几年聚乙烯醇接枝聚合物的研究进展。详细介绍了各类聚乙烯醇接枝聚合物的制备方法和用途。分析了改性后的接枝聚合物相对于原来材料的优越性,并展望了聚乙烯醇接枝聚合物的发展前景。更多还原

【Abstract】 Poly vinyl alcohol (PVA) is commonly used as the biocompatible material,but the defects of PVA are high melting point,poor workability,etc. The studies on the modifications of PVA are attractive at present. The recent research progress in the chemical modifications of poly vinyl alcohol is summarized.The preparation methods and relative application of the poly vinyl alcohol grafted polymers are given in detail,The grafted polymers are more useful than the original materials,the development of PVA-g-polymers are bright prospects.更多还原
