摘要：
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 an organic phosphite cocatalyst. 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.
