Abstract:
A random copolymer comprising monomer units of ethylene, an .alpha.-olefin and a branched conjugated polyvalent olefin,wherein said random copolymer has 0<ethylene monomer units<100 (% by mol), 0<.alpha.-olefin monomer units<100 (% by mol); an iodine value whereby 0<iodine value<370 (g/100 g), an intrinsic viscosity (.eta.) measured in decahydronaphthalene at 135.degree. C. which satisfies the following:0.1 (dl/g)<.eta.<10 (dl/g);and a molecular weight distribution (Mw/Mn).ltoreq.5,wherein the .alpha.-olefin monomer is at least one aliphatic unsaturated hydrocarbon having 3-10 carbon atoms; andwherein the copolymer is obtained by copolymerizing the monomer units of ethylene, .alpha.-olefin and the branched conjugated polyvalent olefin using, as a catalyst, a complex of the group 4 transition metal.
