| 摘 要： | 本文报导了一种用于乙丙共聚的高活性负载型催化剂(TiCl4-FCl3)/MgC12-Al(C2H5)3利用催化剂中PCl3的配体效应和反应过程中的氢调作用,得到低分子量,窄分子量分布的乙丙共聚物,适宜于用作润滑油的粘度指数改进剂。它在粘度指数、增稠能力、低温粘度、热安定性、氧化安定性以及剪切稳定性等使用性能上具有较好的综合指标。

| Abstract: | A highly active supported catalyst (TiCl4-PCl3)/MgCl2-AlEt3 for ethylene-propylene copolymerization is reported. Ethylene-propylene copolymer withlow molecular weight and narrow molecular weight distribution has beenobtained through the addition of PCl3 ligand in the catalyst system andthe hydrogen regulation in the course of reaction. The copolymer is sui-table for viscosity index improver for lubricating oil, having rather goodoverall properties in respect of viscosity index, thickness, low temperatureviscosity, and stabilities against shearing, oxidation. heat etc.. |
