PURPOSE: A catalyst is provided to represent a high activation and a high production rate in a copolymerization reaction and in slurry polymerization reaction and in a copolymerization reaction and also in moving gas phase polymerization reaction of olefin. CONSTITUTION: A catalyst contains a carrier, alumoxane and one or more of metallocene and the catalyst is a shape of free-flowing corpuscle, contains a dried power particle having 1-250 micron of an average particle size. The catalyst containing single transition metal as a shape of metallocene has an activation represented kg unit of a polymer of each transition metal 1g. An amount of metallocene in the phase of the carrier is 0.001-10wt% based on the transition metal element. So, the ratio of Al: Zr of the catalyst can be 25-10,000 and generally 70-980. Herein, the carrier material is porous inorganic material such as silicon or oxide of aluminum. |
