ABSTRACT:
A catalyst composition for the polymerization of Nylon 6 from caprolactam comprising a primary catalyst which comprises an alkali metal hypophosphite or an alkaliearth metal hypophosphite, and an amine cocatalyst. The amine cocatalyst can be selected from the group consisting of phenylene diamines, hindered amines, poly(hindered amines), Group I benzotriazoles, and Group I benzotriazoles. The catalyst composition of this invention is most useful when used in conjunction with the reactive extrusion technology which requires a very fast polymerization rate to take full advantage of this evolving technology.
