ABSTRACT:
A catalyst composition for the polymerization of polyamide/copolyamide comprising a primary catalyst which comprises an alkali metal hypophosphite or an alkali-earth metal hypophosphite, and a cocatalyst which comprises an amine compound. The cocatalyst amine compound is selected from the group consisting of phenylene diamines, hindered amines, poly(hindered amines), and 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.
