Abstract
Described herein is a prepolymerized catalyst encapsulated with macromolecular monomers which is prepared by adding olefin mononers and diene compounds to a solid complex titanium catalyst for olefin polymerization and then polymerizing, and also relates to a method for polymerization or copolymerization capable of preparing polyolefins with high melt strength by polymerizing the olefin by using said catalyst.
