| 摘 要： | 研究了硫醇的种类,用量及加入方式对反应速率、分子量及分子量分布的影响,结果表明,除叔四、八碳硫醇使反应速度降低外,其它均无影响;叔十二碳硫醇是较为理想的分子量调节剂,改变其用量可以适当调整分子量;增量法是实现高转化率、控制分子量、保证产品质量的有效措施。

| Abstract: | It was investigated systematically that the kind, amount, and the addition form of analogous mercaptan affected the molecular parameter of polymer, the polymerization rate and the copolymer composition. It was shown that if the amount of mercaptan increased and mercaptan was added in batches, the molecular weight increased slowly during the latter stage of polymerization and the molecular weight distribution narrowed. |
