Abstract
A thermoplastic resin composition materialincludes a resin portion (a)made of a thermoplastic resin (A); elastomer portions (b)made of a thermoplastic elastomer (B) having substantially no compatibility with the thermoplastic resin (A) and having a glass transition temperature of lower than or equal to −40° C.; and polymer portions (c)made of a high polymer (C) having substantially no compatibility with the thermoplastic resin (A) and the thermoplastic elastomer (B), having a glass transition temperature or crystallization temperature of lower than or equal to −50° C., and having a viscosity at 40° C. of 0.1 to 200000 cP. The material has a structure in which the elastomer portions (b)are dispersed in the resin portion (a), and the polymer portions (c)are dispersed in the elastomer portions (b) Accordingly, low-temperature impact resistance can significantly be improved without deterioration in the other inherent excellent physical properties of the thermoplastic resin.
