含氧单体和1－烯烃配位共聚合研究及共聚物表征

考察了极性含氧单体，４－戊烯氧基三甲基硅烷（ＰＴＭＳ）的络合Ⅱ型ＴｉＣｌ３Ａｌ（ｉ－Ｃ４Ｈ９）３催化体系下与丙烯共聚合情况，通过脱三甲基硅保护基，合成了丙烯，戊烯醇共聚物，并用ＩＲ，ＮＭＲ等方法进行表征，详细考察了Ａｌ／Ｔｉ比，温度等聚合条件对共聚合的影响。初步研究了共聚合的动力学行为，此外，还发现丙烯，戊烯醇共聚物保护了较好的物理性质，如较高的熔点，等规度，抗降解能力，粘接性等，为聚烯烃功能化提

INVESTIGATIONS ON COORDINATION COPOLYMERIZATION OF OXYGEN-CONTAINING MONOMER WITH 1-OLEFIN AND CHARACTERIZATION OF THE COPOLYMER

Copolymerization of propylene with oxygen-containing monomer, 4-pentenoxyl trimethyl silane(PTMS), was studied under Solyay TiCl₃/AI(i-C₄H₉)ca catalyst system. Poly (propylene-co-pentenol) was synthesized by deprotecting trimethyl silica group, and characterized by IR, NMR method. The effect of polymerization condition, e.g., Al/Ti ratio, temperature etc., on the copolymer composition and yield was studied. The copolymerization kinetics was satisfied with that of propylene with l-olefin. Furthermore, the copolymer was found having good physi-cal properties,such as high melting point,isotacticity, crystallinity, good adhesive ability and antidegrading ability.
