ABSTRACT:
A thermoplastic resin composition which has low rigidity such as bending strength, bending modulus and tensile strength, high impact resistance, and further low stress and large energy absorption at the time of impact, high heat deformation resistance and excellent moldability and comprises 5 to 65 by weight of the copolymer (I) having Tg (glass transition temperature) of not more than 20.degree. C., 20 to 80 parts by weight of the maleimide copolymer (II) and 15 to 75 part by weight of the graft copolymer (III) having a graft ratio of 10 to 70% so that the total amount of the copolymers (I), (II) and (III) becomes 100 parts by weight, can be obtained.
