ABSTRACT:
The present invention is a thermoplastic elastomeric resin granule for powder molding having a longer diameter of 400 μm or less and a ratio of the longer diameter to a shorter diameter of from 3:1 to 1:1, wherein said granule comprises a composition prepared by dynamically vulcanizing100 parts by weight of (a) a block copolymer consisting of at least two polymeric blocks (A) composed mainly of a vinyl aromatic compound and at least one polymeric block (B) composed mainly of a conjugated diene compound, and/or a hydrogenated block copolymer obtained by hydrogenating said block copolymer,20 to 300 parts by weight of (b) a non-aromatic softening agent for rubber, and10 to 150 parts by weight of (c) a peroxide-decomposing olefinic resin and/or a copolymer thereof. The resin granule has excellent fluidity in a powder molding.
