摘要

Abstract

Ziegler-Natta precatalysts were synthetized from Lewis-base-modified-MgCl

supports and treated by various Lewis acids

prior to activation by triethylaluminum

in order to increase their activity in ethylene polymerization. BCl

provided the highest increase in activity. Interestingly

polymerization results showed no substantial modification of polymer properties

which is consistent with that Lewis acid only promotes the creation of new active sites

after activation by TEA

possessing very similar features to the original ones achievable with conventional precatalysts (

i.e

. without Lewis-acid treatment).
