摘　　要：本文研究聚乙烯醇与丙基乙烯基亚砜经Michael加成反应合成含亚砜基的改性聚乙烯醇功能高分子.用IR、~1H-NMR、X-射线衍射等鉴定反应产物.结果表明,随着亚砜基含量的增加聚合物的结晶性降低,而在冷水,DMSO,CH_3OH,C_2H_5OH和CH_2Cl_2中的溶解性提高.Michael addition reaction between poly (vinyl alcohol) (PVA) and propyl vinyl sulfoxide (PrVSO) was studied in sodium hydroxide aqueous solution. The functional polymer with various sulfoxide contents were synthesized and characterized by means of IR, 1H-NMR, X-ray diffraction and thermal analysis, etc. The results showed that crystallinity of the functional polymer decreased with increasing content of sulfoxide group in the polymer, and its solubility in cold water, dimethylsulfoxide, methanol, ethanol and dichloromethane was enhanced.
