Aqueous preparation of polyamide with catalyst mixture |
摘要 |
A polyamide/copolyamide catalyst composition comprising a primary catalyst which comprises an alkali metal hypophosphite or an alkali-earth metal hypophosphite, and a cocatalyst which comprises an organic salt or an inorganic salt. 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.
