PURPOSE:To provide a resin compsn. which gives moldings having excellent dimensional accuracy and surface smoothness and a complicated shape, by adding a specified additive to a heat-resistant ABS resin. CONSTITUTION:A heat-resistant ABS resin compsn. having improved moldability is obtd, by adding 2-10pts.wt dicyclohexyl phthalate to 100pts.wt. heat-resistant ABS resin. By adding the addivie to the resin, a resin compsn. can be obtd. which has improved fluidity and moldability and gives moldings having excellent dimensional accuracy and surface smoothness and a complicated shape without detriment to gloss and resistance to chemicals and impact inherent to the resin.
