| 摘 要： | 本文研究了苯乙烯-丙烯腈无规共聚物（SAN）在二氧六环（DOA）中的碱解行为.结果表明聚乙二醇（PEG）能促进SAN的碱解，尤其是促进腈基转化为酰胺基；随反应时间的增加，酰胺基进一步转化为羧基；PEG分子链长对于SAN碱解的促进作用具有重要影响.

| Abstract: | The alkaline degradation behaviors of styrene-acrylonitrile random copolymers (SAN) in 1,4-dioxane (DOA) have been investigated. Results prove that poly(ethylene glycol) (PEG) could obviously enhance the alkaline degradation of SAN. Especially, it could promote the conversion of nitrile groups to amide groups. Moreover, the amide groups were further converted to carboxylic groups with the increase of reaction time. In addition, the chain length of PEG has important effects on the alkaline degradtion of SAN. |
