    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 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 II benzotriazoles. 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.

    摘要： The present invention relates to a process for preparing enzymatically debranched starch by mixing natural starch, water and polyalcohol to form a starch mixture, adding α-1,6-D-glucanohydrolase to debranch the natural starch under 50˜70° C., and terminating the debranching reaction by increasing the temperature of starch mixture. The process of this invention can achieve the purpose of degrading starch to lower molecular weight, while raising amylose content of starch so that the plasticity of starch is increased.

    摘要翻译： 本发明涉及通过混合天然淀粉，水和多元醇以形成淀粉混合物来制备酶促脱支淀粉的方法，在50-70℃下加入α-1,6-D-葡聚糖水解酶来分解天然淀粉，以及 通过增加淀粉混合物的温度来终止脱支反应。 本发明的方法可达到降低淀粉降低分子量的目的，同时提高淀粉直链淀粉含量，使淀粉的可塑性提高。
