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 in the catalysts and the catalytic activity has been examined. Copolymerization of ethylene with linear 1-alkenes by the catalysts was investigated. It was found that hexene-1 and octene-1 were highly incorporated,while for decene-1,the copolymers contained low comonomer component. 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.
