Process Improvement on the Synthesis of 2-Methyl-3-propanesultone;
2-甲基-3-丙烷磺内酯的合成工艺改进
A polymer of poly(ethylene covinyl alcohol) end-capped with potassium sulfonate(EVOH-SO3K) is synthesized by sulfonification of poly(ethylene-co-vinyl alcohol)(EVOH) with 1,3-propane sultone.
以叔丁醇钾为催化剂由聚乙烯-乙烯醇(EVOH)和1,3-丙烷磺酸内酯合成了EVOH磺酸钾离子聚合物(EVOH-SO3K),采用示差扫描量热仪(DSC)、凝胶渗透色谱仪(GPC)测定了EVOH磺酸钾的玻璃化转变温度(Tg),重均分子量(Mw)。
