摘要

THERMOPLASTIC ELASTOMER POWDER FOR POWDER SLUSH MOLDING, POWDER SLUSH MOLDING METHOD USING THE SAME AND MOLDED ARTICLE THEREOF A thermoplastic elastomer powder for powder slush molding, comprising an elastomer composition of an ethylene-.alpha.-olefin copolymer rubber and a polyolefin resin, wherein said elastomer composition has a complex dynamic viscosity ?*(1) as measured at a frequency of l radian/sec in a 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: n = ¢log?*(1) - log?*(100)!/2.
