摘要：
Gel-type poly(styrene-co-divinylbenene) beads (PS bead) were used as a carrier to encapsulate metallocene catalysts through a simple swelling,shrinking procedure. The catalytic species were homogeneously distributed in the PS bead particle. The catalyst exhibited high and stable ethylene polymerization and ethylene/1-hexene copolymerization activity affording uniform spherical polymer particles (1 mm). Polymerization rate profiles exhibited slow initiation and stable increase in polymerization activity with time.
