采用阴离子聚合方法，以环己烷为溶剂、以 THF 为结构调节剂、以 SiCl4为偶联剂，在60℃下反应4 h，制备了低胶液粘度微凝胶含量的两个牌号低顺式聚丁二烯橡胶 LCBR-425和 LCBR-435，胶液粘度分别为25和35 mPa·s，凝胶含量≤150μg/g。并采用两个牌号 LCBR 及日本旭化成公司的低粘度产品 Asaprene 720A（胶液粘度25 mPa·s），以本体法合成 HIPS 和 ABS。结果表明，在相同的反应条件下，采用 LCBR-425和LCBR-435制备的 HIPS 和 ABS 性能优异，产品物理机械性能达到或超过采用 Asaprene 720A 所制备的 HIPS 和ABS 的各项指标。

By anionic polymerization method, using cyclohexane as solvent,THF as structure modifier, SiCl4 as coupling agent,low-cis polybutadiene rubber LCBR-425 and LCBR-435 were prepared in the reactor under the conditions as follows: reaction time 4 h and temperature 60 ℃. The viscosities of LCBR-425 and LCBR-435 were 25 mPa?s and 35 mPa?s,respectively. And gel content was not more than 150μg/g. LCBR-425, LCBR-435 and Asaprene 720A (viscosity 25 mPa?s) were respectively used as raw material to synthesize HIPS and ABS by mass polymerization. The results show that mechanical properties of HIPS and ABS synthesized by LCBR-425 and LCBR-435 can reach or exceed the mechanical properties of HIPS and ABS synthesized by Asaprene 720A under the same condition.
