It is an object of the invention to provide the few ethylene/alpha-olefin copolymer of the double bond amount in a kind of randomness height and copolymer.The ethylene/alpha-olefin copolymer of the present invention is as obtained from the alpha-olefin copolymer for being 3~20 with carbon number in the presence of following olefin polymerization catalysis, by ethene, and the olefin polymerization catalysis includes the crosslinking metallocene compound that formula [I] represents（A）And selected from organo-metallic compound（B-1）, organoalurrunoxy compound（B-2）And can be with being crosslinked metallocene compound（A）React and form the compound of ion pair（B-3）In at least one kind of compound（B）, the ethylene/alpha-olefin copolymer has specific weight average molecular weight, specific molecular weight distribution, specific glass transition temperature and specific B values. |
