POLYESTER RESIN COMPOSITION

摘要

Disclosed is a polyester resin composition having high crystallization rate and excellent moldability. Specifically disclosed is a polyester resin composition containing a polyester resin (a), at least one selected from the group consisting of metal salts (b) of sulfonamide compounds represented by the formulae (1)-(3) below, and an aliphatic carboxylic acid diester compound (c) of a polyalkyleneglycol represented by the formula (4) below. (In the formula, G represents an alkylene group having 2-4 carbon atoms; R⁴ and R⁵ independently represent an alkyl group or alkenyl group having 1-14 carbon atoms; and m represents an integer of 2-30.)
