摘要
Olefins may be polymerised in the presence of a catalytic system comprising a metallocene and an organic aluminum compound supported on a mesoporous material to produce polyolefins. The mesoporous material comprises atoms of one or more elements selected from the group consisting of Group 1, 2, 3 and 5 elements germanium, tin, lead and transition metals. The polyolefins are produced as spherulite particles of average diameter from about 5 &mgr;m to about 20 &mgr;m which have a distinct core and shell arrangement.
