| 摘 要： | 采用DQ-Ⅳ催化剂，在4 L丙烯聚合反应釜进行聚合实验，考察了C-Donor和D-Donor对聚合反应及产品性能的影响。结果表明,其他条件相同时，采用D-Donor作为助催化剂与使用C-Donor相比，催化剂平均活性提高20％～30%，聚丙烯等规度提高平均约1%，催化剂的氢调敏感性降低，聚丙烯结晶温度和熔点显著提高，分子量提高，分子量分布基本未变。

| Abstract: | Influence of C-Donor and D-Donor on propylene polymerization reaction was investigated on a 4 liter reactor using DQ-Ⅳ catalyst. The results showed that, compared with C-Donor, D-Donor enhanced the average catalytic activity by 20%-30%, isotacticity of PP by 1%, lowered the sensitivity to hydrogen, increased the crystallization temperature, melting point and relative molecular weight of PP, with the molecular weight distribution remaining unchanged. |
