Abstract
A method for polymerizing olefins which comprises using a catalyst which comprises, as the essential components, (A) a metallocene-type transition metal compound and (B) at least one member selected from the group consisting of (1) an ion-exchanging layered compound other than a silicate and (2) an inorganic silicate, which is obtained by salt-treatment and/or acid-treatment and which has a water content of not higher than 1% by weight.
