Abstract

A catalyst for polymerizing an olefin, which comprises (A) a metallocene transition metal compound, (B) (1) an ion-exchanging layered compound other than a silicate or (2) an inorganic silicate prepared by treating a starting ion-exchanging layer compound other than a silicate or a starting silicate with a salt, an acid, or a combination thereof, said component (B) having a water content not higher than 1% by weight which is obtained by heat-dehydrating component (B) under an inert gas atmosphere or under reduced pressure, and (C) an organoaluminum compound.
