PROBLEM TO BE SOLVED: To provide a composition based on an ABS polymer, which exhibits such rheological characteristics, particularly a melt index when heated, as to facilitate molding, although compositions based on an ABS polymer and a blend thereof are generally difficult to mold because of the rheological characteristics, particularly low flowability when heated. SOLUTION: This composition contains 100 pts.wt. ABS polymer (A) which can containα-methylstyrene in an amount of up to 60wt.% and has a rubber content of 5-30 pts.wt., and 0.1-12 pts.wt. of at least one polyester represented by the formula (wherein R<1> and R<2> may be the same or different and are each H or a 1-20C alkyl; R<3> and R<4> may be the same or different and are each H or a 1-4C alkyl; R<5> and R<6> are each a 1-6C alkylene; x is an integer of 1 to 4; and n is such a value as to provide a number-average molecular weight of polyester of 800 to 7,000).
