| titleOfInvention | PROCESS FOR PRODUCING .alpha.-OLEFIN POLYMERS USING NOVEL CATALYST SYSTEM |
| abstract | ABSTRACT OF THE DISCLOSURE A process for producing an .alpha.-olefin polymer which comprises polymerizing an .alpha.-olefin in the presence of a catalyst system comprising (A) a solid catalyst component obtained by steps of i) reducing titanium tetrachloride with an organo-aluminum compound represented by the general formula R1nA?Y3-n, wherein R1 represents a C1-C18 hydrocarbon group, Y represents a halogen, and n represents a number satisfy-ing 1 < n < 3, ii) heating the reduction product at a temperature of up to 150°C, iii) treating the thus obtained solid product contain-ing .gamma.-titanium trichloride by preliminary polymerization of an .alpha.-olefin in the presence thereof, and iv) reacting the resulting solid product with a halogen represented by the general formula X2, wherein X represents C?, Br, or I, and/or an interhalogen compound represented by the general formula X'X"a, wherein X' and X" represent each C?, Br, or I and a represents 1 or 3, and with an ether compound represented by the general formula R2-O-R3, wherein R2 and R3 are the same or different and represent each a C1-C10 alkyl group, in a hydrocarbon solvent at a temperature of 50° to 100°C, and (B) an organoaluminum compound. |
