THERMOPLASTIC ELASTOMER COMPOSITION POWDER, POWDER MOLDING PROCESS WITH THE SAME, AND MOLDINGS

摘要

A thermoplastic elastomer composition powder obtained by blending 0.1 to 5 parts by weight of (c) described below per 100 part by weight of a pulverized product of a thermoplastic elastomer composition comprising 10 to 250 parts by weight of (b) described below or 10 to 250 parts by weight of (b) and 0.01 to 10 parts by weight of (d) described below per 100 parts by weight of (a) described below, and having a complex dynamic viscosity eta *(1) of 1.5x10<5> poise or less and a Newtonian viscosity index n of 0.67 or less, and a powder molding process and molded article using said powder. (a): a polyolefin-based resin, (b): a rubbery polymer imparting a new single tan delta peak at a temperature different from that of the tan delta peak of (a) and that of the tan delta peak of (b) within the range of -70 to 30 DEG C in a temperature dependence curve of tan delta determined by solid viscoelasticity measurement of the composition obtained by kneading with (a), and (c): a fine powder having a primary particle size of 300nm or less.
