CMMS和DCPMS在丙烯聚合中的应用

Application of CMMS and DCPMS in propylene polymerization

将CMMS(环己基甲基二甲氧基硅烷)和DCPMS(二环戊基二甲氧基硅烷)外给电子体分别与CS 1型和CS 2型聚丙烯主催化剂进行丙烯聚合评价,结果表明CMMS和DCPMS是高效催化剂的有效助催化剂,它们能够提高聚丙烯的真实等规度。它们提高聚丙烯真实等规度的能力为DCPMS>CMMS>DDS。

CMMS and DCPMS were used as electron donors in combination with CS1 and CS2 propylene polymerization catalysts .The test results showed that CMMS and DCPMS, as two effective promoters for polymerization catalyst, can improve isotacticity of PP in the following order: DCPMS> CMMS >DDS.
