Functional poly(diene sulfone)s are prepared by the radical alternating copolymerization of 1,3‐diene monomers containing an ester substituent with sulfur dioxide. Methyl 3,5‐hexadienoate (MH) and methyl 5,7‐octadienoate (MO) with both an alkylene spacer and a terminal diene structure are suitable to produce a high‐molecular‐weight copolymer in a high yield, while the copolymerization of 5,7‐nonadienoic
功能性聚(二烯砜)是通过将含有酯取代基的1,3-二烯单体与二氧化硫进行自由基交替共聚而制得的。具有亚烷基间隔基和末端二烯结构的3,5-己二酸甲酯(MH)和5,7-辛二烯酸甲酯(MO)适用于高收率地生产高分子量共聚物,而5的共聚包括亚烷基间隔基或末端二烯结构的,7-壬二烯酸,2,4-戊二烯酸乙酯和4-甲基-2-2,4-戊二烯酸乙酯导致未成功的结果。在13MH和MO的C NMR化学位移值表明在它们反应的α碳处具有高电子密度,表现出高共聚反应活性。还制备了含芴的二烯单体9-芴基3,5-己二酸酯(FH)和9-芴基5,7-辛二烯酸酯(FO),并与二氧化硫共聚。研究了在侧链中含有甲基和芴基酯取代基的聚二烯砜的热学和光学性质。©2015 Wiley Periodicals,Inc.
