摘要

THERMOPLASTIC ELASTOMER POWDER FOR POWDER MOLDING, POWDER MOLDING METHOD USING THE SAME AND MOLDED ARTICLE THEREOF A thermoplastic elastomer powder for powder molding, comprising an elastomer composition of an ethylene-.alpha.-olefin copolymer rubber and a polyolefin resin, wherein the elastomer composition has a complex dynamic viscosity ?1*(1) as measured at frequency of 1 radian/sec. in dynamic viscoelasticity measurement at 250.degree.C, of 1.5 x 105 poise or less, a Newtonian viscosity index n calculated from the following formula by using the complex dynamic viscosity ?*(1) at a frequency of 1 radian/sec. and the complex dynamic viscosity ?*(100) at a frequency of 100 radian/sec. of 0.67 or less, and a hardness (shore D) of 45 or less: n = {log?*(1) - log?*(100/2.
