Abstract
Provided are a catalyst component for olefin polymerization which is highly active, an olefin polymerization catalyst, and a process for producing an olefin (co)polymer using the catalyst. The catalyst component for olefin polymerization is characterized by comprising an ion-exchanged phyllosilicate having the property 1 and preferably further having the property 2, etc.
Claims10
A catalyst component for olefin polymerization, comprising an ion-exchanged phyllosilicate having the following property 1,
- Property 1:
- in a pore distribution curve calculated by the BJH analysis method using an adsorption isotherm determined by a nitrogen adsorption method, the sum of the volumes of pores each having a diameter of 2-10 nm accounts for 60-100% of the total volume of mesopores.
