摘要：
A method for the polymerization of Nylon 6 from caprolactam and water using a catalyst composition comprising a primary catalyst, which can be an alkali metal hypophosphite or an alkali-earth metal hypophosphite, and an organic phosphite as cocatalyst. The catalyst composition used in 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.
