<p><P>PROBLEM TO BE SOLVED: To provide a new material excellent in fluidity and moldability, which allows, as a single component (without requiring other polymer components), formation of automobile industrial parts, industrial rubber products, electric insulating materials, civil engineering and building materials and rubber products such as rubberized cloth. <P>SOLUTION: An ethylene copolymer is provided, including structural units derived from ethylene [A],α-olefin [B] having 3 to 20 carbon atoms and at least one kind of non-conjugate polyene [C]. The content of the structural unit derived from ethylene [A] and of the structural unit derived from the non-conjugate polyene [C] in 100 mol% of the whole structural units of the copolymer is in a given range. The ethylene copolymer has limiting viscosity [η] of 0.25 to 0.55 dL/g measured in a decalin solution at 135°C and an inversion value of 0.01 to 0.50. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
