Title:
BRIDGED METALLOCENE COMPOUND, OLEFIN POLYMERIZATION CATALYST USING THE COMPOUND AND ETHYLENE POLYMER OBTAINED BY USING THE CATALYST
Document Type and Number:
WIPO Patent Application WO/2009/066689
Kind Code:
A1
Abstract:
It relates to a metallocene compound useful as an olefin polymerization catalyst
or catalyst component, and an olefin polymerization method using an olefin polymerization
catalyst containing the metallocene compound. More particularly, it relates
to an olefin polymerization catalyst capable of producing an olefin polymer
having a high melt tension, excellent mechanical strength and excellent particle
properties with a high polymerization activity, an olefin polymerization method
using this catalyst, an ethylene polymer which is obtained by the polymerization
method and is excellent in moldability, easy openability, and particularly
excellent in mechanical strength as compared with conventionally known ethylene
polymers, and a thermoplastic resin composition containing the ethylene polymer.
More particularly, it provides a molded article and a film formed from the ethylene
polymer or the thermoplastic resin composition containing the ethylene polymer,
and a laminate film comprising the film. It provides an olefin polymer which
shows little neck-in in T-die molding, does not cause take-off surging, is particularly
excellent in mechanical strength, and has a large number of long-chain branches
caused by simultaneously inducing production of a macromonomer as a source of
long-chain branches and repolymerization of the produced macromonomer in the
coexistence of a single type or plural types of bridged metallocene compounds
including a group derived from a cyclopentadienyl group having a different structure
in the same polymerization system, an olefin polymerization catalyst and a polymerization
method capable of efficiently producing the olefin polymer.
