(57) [Summary] [Structure] C 2-20 α-olefin and formula, CH 2 = CH -C n H 2n -X (wherein, X = OH, SH, COOH , N The H 2, NHR 1 or NR 1 2, n is an integer of 1 to 20, R 1 represents a C 1-20 hydrocarbon group), in the copolymerization under contact with a polar vinyl monomer, the polar vinyl monomer is preliminarily contacted with an equimolar amount of AlR 2 R 3 R 4 and then polymerized. And the catalyst is component (A) = A method for producing an α-olefin copolymer, which is a combination of an IVB to VIB transition metal compound having at least one conjugated five-membered ring and a component (B) = an organoaluminum oxy compound. [Effect] An α-olefin copolymer containing a polar vinyl monomer in a high content and excellent in adhesiveness, printability, hydrophilicity and compatibility in a polymer blend can be obtained in a high yield. |
