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 Å; andfeature 2: in a pore size distribution curve calculated from desorption isotherm by nitrogen adsorption-desorption method, a pore diameter Dm1/2 (Å) on the smaller pore size side corresponding to a ½ 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.
