摘要
采用过氧甲酸原地法、过氧乙酸原地法及单过氧邻苯二甲酸MPPA法合成了一系列具有不同环氧值的液体环氧化聚丁二烯 (LEPB) ,探索了温度、反应时间对环氧化反应影响的规律 ,并通过开环几率和双键反应程度对环氧化反应进行了详细的讨论。IR和NMR谱结果表明 ,1,4-结构双键的环氧化活性高于 1,2
A series of liquid epoxidized polybutadiene (LPB)with various epoxy value had been synthesized through epoxidation by peroxyformic acid in situ,peracetic acid in situ and mono peroxyphthalic acid(MPPA).The effective regularities of reaction time and temperature on epoxidation reaction were discussed and explained by ring opening probability and reaction extent of double Bond with.IR and NMR analyses and showed that the epoxidation reactivity of 1,4-double bond was higher than that of 1,2-double bond.
