Process Improvement on the Synthesis of 2-Methyl-3-propanesultone;

2-甲基-3-丙烷磺內(nèi)酯的合成工藝改進(jìn)

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.

以叔丁醇鉀為催化劑由聚乙烯-乙烯醇(EVOH)和1,3-丙烷磺酸內(nèi)酯合成了EVOH磺酸鉀離子聚合物(EVOH-SO3K),采用示差掃描量熱儀(DSC)、凝膠滲透色譜儀(GPC)測定了EVOH磺酸鉀的玻璃化轉(zhuǎn)變溫度(Tg),重均分子量(Mw)。
