摘要
G P C 法研究了低顺式聚丁二烯( L C B R) 的相对分子质量分布,同时确定了日本 Asaprene 730 A 的 L C B R 为4 支化星形聚合物。用偶联法合成了 L C B R,并用 G P C 分布曲线指导中试放大实验。
The relative molecular mass distribution of low cis-1,4 -polybutadiene rubber (LCBR) was studied by GPC.The LCBR of Japan Asaprene 730 A was defined as 4 star branched polymer,LCBR was synthesized by coupling polymerization and pilot-plant test was guided by the distribution curves of GPC.
