<P>PROBLEM TO BE SOLVED: To provide an α-olefin-conjugated diene copolymer having a low gel fraction, a high molecular weight, and a high utility value, and a method for producing the same. <P>SOLUTION: The α-olefin-conjugated diene copolymer has a gel fraction of 5% or less calculated by measurement of a gel content having a size of 0.45 μm or more in a diluted THF (tetrahydrofuran) solution and Mooney viscosity (ML<SB POS="POST">1+4</SB>/100°C) of more than 80. <P>COPYRIGHT: (C)2012,JPO&INPIT |
