Abstract
A non-crystalline resin composition possessing rubberlike elasticity, prepared by homogeneously mixing (1) 100 parts by weight of a vinyl chloride polymer, with (2) 110 to 160 parts by weight of a thermoplastic polyester-urethane formed by reacting an organic diisocyanate with a polyester diol having a molecular weight of at least 4000, said polyester diol having been formed by reacting a polyol component comprising 1,6-hexanediol and a low molecular weight diol having a side-chain methyl group at a mixing molar ratio of from 70 : 30 to 90 : 10, with a saturated aliphatic dicarboxylic acid having 5 to 8 carbon atoms.
