URETHANE RESIN PARTICLES |
摘要 |
Provided is a slush molding material which exhibits excellent low-temperature meltability and heat resistance and which can yield a molded product having excellent tensile strength and elongation. The present invention is urethane resin particles (D1) comprising a urethane or urethane-urea resin (U1) that has residues (j) bonded thereto covalently, said residues (j) being residues derived from an at least trivalent aromatic polycarboxylic acid by removing hydroxyl groups, or urethane resin particles (D2) comprising a urethane resin composition (S2) which comprises both a urethane or urethane-urea resin (U2) and a compound (E) that has a residue (j) derived from an at least trivalent aromatic polycarboxylic acid by removing hydroxyl groups, said compound (E) being represented by general formula (1), wherein the residues (j) are linked respectively to urethane or urea groups (u) of the resin (U1) or (U2) by hydrogen bonds. |
