| titleOfInvention | CATALYST FOR POLYMERIZATION OF AN OLEFIN, METHOD FOR PRODUCING POLYMER OF OLEFIN AND PROPYLENE-alpha-OLEFIN COPOLYMER |
| abstract | A catalyst for polymerization of an olefin is disclosed, including a compound represented by the general formula R 1 R 2 Si(NHR 3 ) 2 wherein R 1 is a cycloalkyl group having 3 to 12 carbon atoms or an aromatic hydrocarbon group having 6 to 12 carbon atoms; R 2 is a linear alkyl group having 1 to 10 carbon atoms or a branched alkyl group having 3 to 10 carbon atoms; the number of carbon atoms of R 1 is larger by 2 or more than that of R 2 ; and R 3 is a linear alkyl group having 2 to 6 carbon atoms, a branched alkyl group having 3 to 6 carbon atoms or a cycloalkyl group having 3 to 6 carbon atoms, as an external electron-donating compound. The catalyst can prepare a polymer having excellent hydrogen activity and high stereoregularity and melt flow rate even in homopolymerization at a high temperature, with high productivity. |
