| 中文摘要: |
| 考察了苯乙烯类嵌段共聚物对IR/CR二元共混物相态结构及粒子尺寸的影响。结果表明，加入苯乙烯类嵌段共聚物可有效改善IR/CR共混物的分散状态，在任何组成下均可降低分散相粒子尺寸，促进体系均匀分散，其中苯乙烯-异戊二烯共聚物的效果最为理想，其最佳用量为3～7份。 |
| 英文摘要: |
| The influence of styrene-based block polymers on the phase structure and the particle size of IR/CR blend was investigated. The results showed that the distribution of IR/CR blend was improved，the size of the particles in the discontinuous phase was decreased and a uniform dispersion of accelerator was obtained by the addition of styrene-based block polymers. Among the tested styrene based block polymers，Styrene-isoprene copolymer was the most effective and the optimum level was 3～7 parts. |
