异戊橡胶的序列结构及其与结晶性能的关系

研究了几种不同牌号的异戊橡胶（IR）的序列结构及其与结晶性能之间的关系.结果表明,不同牌号的IR具有不同的序列结构,而序列结构的不同导致IR的结晶性能存在差异,其中高顺式-1,4-结构的IR具有良好的结晶性能,而反式-1,4-结构和3,4-结构的存在会降低IR分子链的规整度,不利于结晶....

The relationship between the sequence structure of different brands of polyisoprene （IR） and their crystallization performance was studied.The results showed that there was different sequence structures among different brands of IR,which led to different crystallization performances.IR with high content of cis-1,4-unit had good crystallization
