樹脂組成物を与える。 If the base polymer consists of 95% by weight or more of polyamide resin and 5% by weight or less of ethylene-vinyl acetate copolymer resin and/or its partially saponified product, no effect of the combination will be seen, and if the polyamide resin is 50% by weight In the case of a base polymer consisting of 50% by weight or more of the following and an ethylene-vinyl acetate copolymer resin and/or a partially saponified product thereof, the matrix of the composition is an ethylene-vinyl acetate copolymer resin and/or a partially saponified product thereof. This is not preferable because the characteristics of the polyamide resin are lost. When the polyether ester amide elastomer added to these base polymers is added to 100 parts by weight of the base polymer, there is almost no effect of improving compatibility when the amount is less than 5 parts by weight, and when it is added to 40 parts by weight or more, compatibility is again inhibited. The effect of solubility improvement becomes worse, and the best effect is obtained when 5 to 40 parts by weight, especially 5 to 20 parts by weight, is added. is uniformly dispersed with a particle size on the order of 1 micron or less, providing a tough thermoplastic resin composition.
