Abstract

PURPOSE: The titled sizing agent that is composed of modified polyamide obtained by polymerization of α-(N,N-dimethylamino)-ε-caprolactam, thus showing good adhesion to matrix, handleability in processing and fluffing prevention.
CONSTITUTION: α-(N,N-dimethylamino)-ε-caprolactam alone or a mixture of 30W 100wt%, preferably 40W100% α-(N,N-dimethylamino)-ε-caprolactam with at least one of cyclic amides of the formula (n is 3W11; R is alkyl) such as ε-caprolactam is polymerized by heating in the presence of 1W5wt%, based on the monomer, of a catalyst such as sodium amide and a cocatalyst such as N-acetyl- ε-caprolactam in an inert gas atmosphere. The resultant modified polyamide is dissolved in an acidic aqoeuos solution, preferably in 0.5W30% concentration to give the objective sizing agent.
