Abstract
A method for manufacturing a heat resistant resin composition having superior dispersibility of maleimide-based copolymer, the method including: a melt-kneading step to melt and knead a maleimide-based copolymer (A) and at least one resin (B) selected from the group consisting of ABS resin, ASA resin, AES resin, and SAN resin with an extruder; wherein: a ratio of a melt viscosity of the maleimide-based copolymer (A) with respect to a melt viscosity of the resin (B) obtained with a shear rate of 120/sec and a cylinder temperature of a kneading unit of the extruder is 1.0 or higher and lower than 3.4, is provided.
