高选择性透过二氧化硫气体分离膜的研究（Ⅲ）──乙烯基亚砜与聚乙烯醇的Michael加成反应及其结构表征

Studies on High Permselective Gas Separation Membrane of Sulfur Dioxide(Ⅲ)──Michael Addition Reaction of Vinyl Sulfoxide with Poly(vinyl alcohol) and Structure Characterization

本文合成了４种烷基乙烯基亚砜，研究了其与聚乙烯醇在碱催化下的Ｍｉｃｈａｅｌ加成反应，制备了不同亚砜含量的聚合物。研究了其溶解性能，用ＩＲ及＾１Ｈ ＮＭＲ法对聚合物进行了表征。

Four kinds of alkyl vinyl sulfoxides were synthesized.The Michael addition reaction of vinyl sulfoxide with poly(vinyl alcohol) in the presence of NaOH as catalyst has been studied in detail.Polymers with various sulfoxide contents were prepared and characterized by means of 1H NMR and IR spectra.
