摘要

COMPOSITE FOAM MOLDED ARTICLE, PROCESS FOR PRODUCTION THEREOF, AND FOAMABLE POWDER COMPOSITION An integrally molded composite article comprised of (I) a nonfoam layer formed from a thermoplastic elastomer powder composition (A) and (II) a foam layer formed from a foamable composition comprised of (i)(B) a thermoplastic synthetic resin powder, and (C) a heat decomposable foaming agent or (ii)(B) a thermoplastic synthetic resin powder, (C) a heat decomposable foaming agent and (D) a liquid coating agent, wherein the thermoplastic elastomer powder (A) is comprised of a composition of an ethylene-.alpha.-olefin copolymer rubber and a polyolefin resin or a thermoplastic elastomer powder comprised of a partially cross-linked composition of an ethylene .alpha.-olefin copolymer rubber and a polyolefin resin, the thermoplastic elastomer powder having a complex dynamic viscosity ?* (1) at 250.degree.C and a frequency of 1 radian/sec of not more than 1.5 x 105 poise and having a Newtonian viscosity index n, calculated by the following formula using the above-mentioned complex dynamic viscosity ?* (1) and the complex dynamic viscosity (100) at a frequency of 100 radians/sec, of not more than 0.67: n = {(log?*(1)-log?* (100/2.
