COMPONENT OF CATALYST FOR OLEFIN POLYMERIZATION

摘要

A catalyst component for olefin polymerization, which comprises an ion-exchange layered silicate having the following features 1 and 2: feature 1: in a pore size distribution curve calculated from desorption isotherm by nitrogen adsorption-desorption method, a pore diameter Dm showing a maximum peak intensity DVM is from 60 to 200 ANGSTROM ; and feature 2: in a pore size distribution curve calculated from desorption isotherm by nitrogen adsorption-desorption method, a pore diameter Dm1/2 ( ANGSTROM ) on the smaller pore size side corresponding to a 1/2 peak intensity of the maximum peak intensity DVM has a relation of Dm1/2/Dm of at least 0.65 and less than 1, provided that the largest value is employed when there are a plurality of Dm1/2 values.
