摘要
开发一种改进的N -3型聚丙烯高效催化剂 ,可通过调节催化体系的Al/Si摩尔比来调节聚丙烯树脂等规度。Al/Si摩尔比从 2 0提高到 90 ,树脂等规度从～ 97%降低到～ 95 % 。
A study on isotacticity adjustability of polypropylene resin by using an improved catalyst N-3 and adjusting Al/Si mole ratio of the catalystic system has been carried out.The Al/Si mole ratio is raised from 20 up to 90,and the resin isotacticity is dropped from ～97% down to ～95%,the adjustability is remarkable.
