410苯乙烯-异戊二烯-丁二烯橡胶

Styrene isoprene butadiene rubber (SIBR)

和（B）以重量计约5%至约20%的丁二烯橡胶。

And (B) about 5 to about 20 % by weight of a butadiene rubber.

在模试装置上合成出轮胎用低顺式聚丁二烯橡胶 ( LCBR ).

Low cis - polybutadiene rubber ( LCBR ) was synthesized in experiment.

以苯乙烯-低顺式聚丁二烯橡胶接技共聚制备高抗冲聚苯乙烯。

High-impact polystyrene (HIPS) was prepared by styrene grafting copolymerization on the low cis -polybutadiene rubber.

以苯乙烯-低顺式聚丁二烯橡胶接技共聚制备高抗冲聚苯乙烯。

High - impact polystyrene (HIPS) was prepared by styrene grafting copolymerization on the low cis- polybutadiene rubber.

结果表明，聚丁二烯橡胶的焦烧安全性较好；

The results showed that the scorch safety of polybutadiene rubbers was good;

三中单体的聚合产生了具有两相的三元共聚物，一个是苯乙烯-丙烯腈的连续相，另一个是聚丁二烯橡胶分散相。

The polymerization of the three monomers produces a terpolymer which has two phases: a continuous phase of styrene-acrylonitrile (SAN) and a dispersed phase of polybutadiene rubber.

同时利用示差扫描量热法(DSC ) 研究了天然橡胶、异戊二烯橡胶和顺丁二烯橡胶裂解时的热能变化.

The heat energy of pyrolysis was studied by differential scanning calorimetry ( DSC ) at same time.
