摘　　要：熔融加工是一种相对简单、高效的加工方法。由于聚乙烯醇(PVA)的热分解温度很接近其熔点,使其难以熔融加工。为实现PVA的熔融加工,可以用溶剂增塑、共聚和共混等增塑(改性)技术来达到。近年来,对可熔融加工聚乙烯醇的需求也日益迫切。综述了近年来该领域的研究进展情况。Melt process is a more simple and effective technique for PVA processing. The melt process of polyvinyl alcohol （PVA） is difficult since the decomposion temperature of PVA is very close to its melting point. The several techniques such as solvent plasticization, copolymerization and blending arc used to realize its melt process. The present developments on this subject are introduced in this paper.
