Abstract

Abstract: Supported Zr/MAO/SiO₂ catalysts with different Zr content have been synthe-sized.The influence of the amount of methylaluminoxane in reactants on the Zr content inthe catalysts and the catalytic activity has been examined.Copolymerization of ethylene withlinear 1-alkenes by the catalysts was investigated.It was found that hexene-1 and octene-1were highly incorporated,while for decene-1,the copolymers contained low comonomercomponent.The effect of chain length of α-olfin on the catalytic activity has been explained.It is observed from SEM that α-olefin in the copolymers can improve polymer particle mor-phology.

Key words: supported catalyst, zirconocene, olefin polymerization, catalytic activity
