Thermoplastic elastomer powder for powder slush molding powder slush molding method using the same and molded article thereof

摘要

A thermoplastic elastomer powder for powder slush molding, comprising an elastomer composition of an ethylene-&agr;-olefin copolymer rubber and a polyolefin resin, wherein said elastomer composition has a complex dynamic viscosity &eegr;*(1) as measured at a frequency of 1 radian/sec. in a dynamic viscoelasticity measurement at 250° C., of 1. 5× 10.sup.5 poise or less, a Newtonian viscosity index n calculated from the following formula by using the complex dynamic viscosity &eegr; *(1) at a frequency of 1 radian/sec. and the complex dynamic viscosity &eegr;*(100) at a frequency of 100 radian/sec. of 0.67 or less:P P n=[log&eegr;*(1)-log&eegr;*(100)]/2.
