Title:
CARRIER FOR ALPHA-OLEFIN POLYMERIZATION CATALYST AND PRODUCTION
Document Type and Number:
Japanese Patent JPH06192329
Kind Code:
A
Abstract:

PURPOSE: To obtain the subject carrier having spherical form with narrow particle size distribution and, accordingly, giving a solid catalyst having excellent fluidity and polymerization activity in fluidized bed reactor by reacting a solution of a Grignard compound with a halogenated hydrocarbon compound.

CONSTITUTION: The objective carrier is produced by reacting a solution of a Grignard compound (preferably alkylmagnesium chloride such as methylmagnesium chloride) with a halogenated hydrocarbon compound (preferably a hydrocarbon compound containing Cl-C bond such as chloroform). This reaction is preferably carried out by dissolving the Grignard compound in a hydrocarbon solvent containing ≥20vol.% of an ether having total carbon number of ≥6 (e.g. dipropyl ether), slowly adding the halogenated hydrocarbon to the obtained solution at ≤60°C slowly raising the reaction temperature to ≤50°C under stirring and collecting the precipitated solid particles.
