PROBLEM TO BE SOLVED: To provide a polycapramide copolymer resin composition of high quality that is controlled in generation of a white contaminant at an excellently high level, and a method for manufacturing it stably. SOLUTION: This polycapramide copolymer resin composition comprises a polycapramide copolymer (A) obtained by copolymerization ofε-caprolactam (a1) with at least one dicarboxysulfonate compound (a2) represented by formula (I) (wherein M is a Na atom or a K atom, R and R' are each hydrogen or an alkyl group that may be same or different) of 0.1-3 mol% based on the amount of theε-caprolactam, and an anionic surfactant (B) of 1-100 wt.% based on the unit produced from the dicarboxysulfonate compound. The method for manufacturing it is also disclosed. COPYRIGHT: (C)2008,JPO&INPIT
