<P>PROBLEM TO BE SOLVED: To provide a composition which is excellent in molding processability, and whose crosslinked body is excellent in shape memory and rubber elasiticity. <P>SOLUTION: The composition contains 100 pts.wt of an ethylene-α-olefin-nonconjugated polyene copolymer (A), and 15 to 40 pts.wt of a polymer (B) having as a main component a structural unit originated from one selected from 3-20C α-olefins, wherein the polymer (B) satisfies the following (i) and (ii). (i) The melting point measured by a differential scanning calorimeter (DSC) is 125 to 245°C. (ii) The number-average molecular weight (Mn) in terms of polystyrene, measured by gel permeation chromatography (GPC), is 1,000 to 15,000. <P>COPYRIGHT: (C)2013,JPO&INPIT |
