Abstract
The present disclosure provides a leaching process and resulting composition which prevents or substantially reduces agglomeration of polyamide 6/66 copolymers. The leaching process includes applying hot water in the presence of an agglomeration inhibitor to the polyamide 6/66 copolymers in order to separate unreacted caprolactam and small molecular weight oligomers from the copolymers while preventing or substantially reducing agglomeration of the copolymers.
