반응 단계

60 parts by weight of the propylene/ethylene/DCPD copolymer obtained in Polymerization Example 2, 40 parts by weight of a syndiotactic polypropylene (homopolymer, MFR=5.5 g/10 min), 1 part by weight of carbon black masterbatch (for black coloring), 0.2 part by weight of 2,5-dimethyl-2,5-di-(tert-butylperoxy)hexane (as a crosslinking agent), and 0.4 part by weight of divinylbenzene (as a crosslinking aid) were mixed sufficiently with a high speed mixer, and then the mixture was subjected to dynamic crosslinking in a twin-screw extruder maintained at 200° C., to obtain a thermoplastic elastomer composition (C-5). Subsequently, a laminate of the olefinic thermoplastic elastomer (A-1) and the thermoplastic elastomer composition (C-5) was obtained in the same manner as in Example 1.
