Title:
OLEFIN-POLYMERIZATION SOLID CATALYTIC COMPONENT, PRODUCTION METHOD FOR OLEFIN-POLYMERIZATION CATALYST, AND PRODUCTION METHOD FOR OLEFIN POLYMER
Document Type and Number:
WIPO Patent Application WO/2016/121551
Kind Code:
A1
Abstract:
Provided is an olefin-polymerization solid catalytic component that includes an electron-donating compound other than a phthalate ester, that also includes an organic silicon compound, and that, even when a polymerization catalyst is prepared therefrom under an inert gas atmosphere, demonstrates excellent catalytic activity during polymerization and can produce a polymer that has excellent stereoregularity, bulk density, and the like. An olefin-polymerization solid catalytic component that is characterized by being formed by bringing a catalytic component, which comprises a powdered solid component that is obtained by bringing a magnesium compound (a) and a titanium halide compound (b) into contact with one or more electron-donating compound (c) that does not have a phthalate ester structure and has one or more group selected from among an ester group, a carbonate group, and an ether group, into contact with a vinyl silane compound (d), the molar amount of which is 0.1-15 times the molar amount of the titanium halide compound (b) included in the catalytic component in terms of titanium atoms.
