Abstract
A formed thermoplastic resin article is made of a thermoplastic resin and a foamed elastic polymer finely dispersed in the thermoplastic resin. The formed thermoplastic resin article can be produced by blending an elastic polymer, in which an endothermic foaming agent decomposable at a temperature of at least 160.degree. C. was mixed in advance at a temperature lower than a decomposition temperature of the endothermic foaming agent, in a thermoplastic resin and then plasticizing and forming the resultant resin blend at a temperature at least equal to the decomposition temperature of the endothermic foaming agent.
