The present invention provides a resin powder composition for slush molding which can give slush molded articles with more excellent hydrolysis resistance. The present invention relates to a resin powder composition for slush molding which is characterized by comprising as the main component a thermoplastic polyurethane resin powder, preferably a thermoplastic polyurethane elastomer powder, and containing a polycarbodiimide prepared by polymerizing tetramethylxylylene diisocyanate, alkoxy terminated one having a number average molecular weight of 500 to 30,000.

Resin powder composition for slush molding and molded articles

A powdered resin composition for slush molding comprising a thermoplastic polyurethane resin powder (B) as the main component and a fine particle powder (A) of a vinyl type copolymer comprising a copolymer of a monomer (a01) having one vinyl group such as methyl methacrylate and a monomer (a02) having two or more vinyl groups such as ethylene glycol dimethacrylate and having a cross-linked structure; or a fine particle powder (E) of a vinyl type copolymer comprising the (a01) and a monomer (a03) having one or more vinyl groups and one or more functional groups other than a vinyl group such as hydroxyethyl (meth)acrylate and having a cross-linked structure. The fine particle powder is a powder flowability improver which does not cause die stains and the powdered resin composition for slush molding containing the fine powder do not cause staining of molds.

Powdered resin composition for slush molding and molded product

The present invention provides a material for slush molding which is improved in melt properties during slush molding and is excellent in heat resistance, the material being made up of a thermoplastic polyurethane resin (A) the difference between the softening starting temperature (STi) and the softening ending temperature by TMA being from 0 to 30&#xb0; C., and STi being 135 to 200&#xb0; C. The resin (A) has a hard segment with an Mn of 200 to 2000 comprising a diisocyanate having a symmetrical structure, a low molecular-weight diamine having a symmetrical structure, and/or a low molecular-weight diol, the content of which being from 5 to 50 wt %, and a soft segment making up of a high molecular-weight diol with an Mn of 500 to 5000, with the aromatic content being 35 wt % or less and the aromatic ring content x and the urea group content y satisfying&#x2212;0.1+2.5&#x2266;&#x2266;&#x2212;0.1+6.
