摘要

研究了ＭｇＣｌ２载体高效催化剂用于丙烯为主体的与乙烯和丁烯－１的二元及三元共聚合反应：选择了最佳的共聚合条件；实验测定了共聚单体配比对共聚合活性、共聚物分子量和物理性能的影响；并用１３Ｃ—ＮＭＲ分析了共聚物组成、序列分布和支链结构等微观结构信息．

Abstract

Co-and terpolymerization of propylene ethylene and butene-1 with highly efficient supported Ziegler -Natta catalysts were investigated.The polymerization activities depended not only on the reaction temperatured

catalyst concentration and the molar ratio of Al/Ti

[DDS]/[TEA] but also on the monomer's composition It was found that the optimum conditions for the polymerization activities were T=50℃

[Ti]=0.1 mM

Al/Ti= 100

[DDS]/[TEA]=0.1; the activities of propylene with ethylene and butene-1(P-E-B)terpolymerization were higher than those of propylene-ethylene(P-E)or propylene-butene-1(P-B)copolymerization under the same conditions.Effects of the monomer composition on the physical properties of co-and terpolymers were also described.With increasing the concentration of the comonomers

the contents of both ethylene and butene-1 in P-E-B terpolymers as well as P-E

P-B copolymers increased;but the intrinsic viscosity (ηin)

density

melting point and crystallinity of the ptoducts dectrased.Finally

the microstructures of co- and terpolymers were examined by 13C-NMR spectra

which indicated the existence of long propylene chain sequence in the co- and terpolymers.
