オレフィン類重合用触媒およびオレフィン類の重合方法
Document Type and Number:
Japanese Patent JP3989714
Kind Code:
B2
Abstract:
Olefin polymers with a broad molecular weight distribution can be obtained while maintaining the high stereoregularity of the polymers by polymerizing olefins using a catalyst comprising (A) a solid catalyst component prepared by contacting (a) a dialkoxymagnesium, (b) a tetravalent titanium halide compound, and (c) an electron donor compound one another, (B) an organoaluminum compound of the formula R<1>pAlQ3-p, and (C) an aminosilane compound of the formula R<2>R<3>Si (OR<4>)2.
