摘　　要：ＰＶＢ存在下ＰＶＣ化学法脱氯化氢的研究刘恒＊李大成陈朝珍（四川联合大学化工学院成都６１００６５）关键词聚氯乙烯，脱氯化氢，聚乙烯醇缩丁醛１９９６－０９－０８收稿，１９９７－０５－２６修回国家教育委员会留学归国人员资助费资助课题近年来在ＰＶＣ脱氯化氢制...PVC has been dehydrochlorinated by alkali alkoxide in the presence of poly(vinyl butyral)(PVB). Effects of time, reagents and PVB on the reaction have been studied. The solution and product was analyzed by UVVis spectrophotometry and FTIR. A highly dehydrochlorinated PVC and stable product with long trans(CH)x chain sequences has been found.
