三氯化硼－四氢呋喃络合物催化二乙氨基环硫丙烷的聚合反应

三氯化硼－四氢呋喃络合物催化二乙氨基环硫丙烷的聚合反应 POLYMERIZATION OF DIETHYLAMINO EPITHIOPROPANE CATALYZED BY BORONTRIFLUORIDE-TETRAHYDROFURAN 徐羽梧 1 first-author 王颖 1 武汉大学化学系 武汉大学化学系 Department of Chemistry,Wuhan University Department of Chemistry,Wuhan University 研究了二乙氨基环硫丙烷在三氟化硼－四氢呋喃络合物（ＲＦ３·ＴＨＦ）催化下的聚合反应．与使用ＢＦ３·Ｅｔ２Ｏ作催化剂时聚合物沉淀析出的情况不同，在ＢＦ３·ＴＨＦ催化下，可得到均相粘性聚合物，而且部分四氢呋喃参与了共聚合反应．通过改变催化剂和溶剂的用量以及单体的加料方式制得了一系列组成和分子量不同的共聚物，用元素分析、核磁、红外、分子量测定等测试手段对聚合物进行了表征，还讨论了聚合反应的机理． The copolymerization of diethylaminoepithiopropane with tetrahydrofuran catalyzed by borontrifluoride-tetrahydrofuran complex was studied.A series of copolymers were obtained and characterized by elementary analysis,IR,1H NMRand molecular weight determination . The results showed that the amount of catalyst ad solvent,as well as the feeding way of monomer affected the composition of copolymers.The mechanism of copolymerization was also discussed. 二乙氨基环硫丙烷 三氟化硼－四氢呋喃络合物 聚合与共聚合 diethylaminoepithiopropane borontrifluoride-tetrahydrofuran complex copolymerization O631.5 国家自然科学基金(61672102) 1995-02-01 2021-04-01 2
