低顺式聚丁二烯橡胶是以烷基锂为引发剂,在非机性溶剂中进行丁二烯阴离子聚合制得的,其顺式-1,4-丁二烯质量分数35%～42%,反式-1,4-丁二烯质量分数50%～55%,1,2-乙烯基质量分数8%～12%。这种合成橡胶与采用其它催化剂制造的顺丁胶BR相比具有明显的特点,例如在分子结构上,低顺式聚丁二烯橡胶顺反异构体呈无规则分布。从理论上讲,低顺式聚丁二烯橡胶有优异的耐寒性、回
Low cis-polybutadiene rubber is alkyllithium as initiator, butadiene anionic polymerization in a non-solvent system, the cis-1,4-butadiene content of 35% to 42 %, Trans-1,4-butadiene 50% ~ 55%, 1,2-vinyl content 8% ~ 12%. This synthetic rubber has the obvious characteristics compared with the butadiene rubber BR made with other catalysts, for example, the cis-isomer of low cis-polybutadiene rubber is irregularly distributed on the molecular structure. In theory, low cis-polybutadiene rubber has excellent cold resistance, back
