摘要
研究了在不同温度下进行丙烯聚合时,催化剂的活性、氢调敏感性及聚合物等规度的变化情况.结果表明,随着聚合反应温度的提高,聚丙烯催化剂的活性增加,定向性提高,A催化剂的氢调敏感性变差,而B催化剂的氢调敏感性增强.
Effects of temperature on activity, isostacticity and hydrogen response of catalyst in propylene polymerization are studied and the performances of catalyst with different temperature are compared. The results show that, with the higher the polymerization temperature, the higher activity and stereospecificity, but lower hydrogen response with A-catalyst can be obtained, and the higher activity, stereospecificity and hydrogen response with B-catalyst can be obtained.
