    • Novel hardening agents for epoxy compounds which are produced by reaction of polyalkylene, polyether amines having a mean molecular weight of 148 to 5,000 with di and/or polyepoxy compounds to a preliminary product, the ratio of the hydrogen atoms possibly remaining after reaction with monoepoxy compounds and bound to nitrogen and which are capable of reaction with epoxide groups, to epoxide groups of diepoxy compounds or polyepoxy compounds in the range of 1:1.4 to 6, and reaction of this preliminary product with a primary or secondary amine, the employed amine or amine mixture being used in an amount such that the ratio of epoxide groups capable of reaction to hydrogen atoms attached to nitrogen is 1:2 to 10.
    • 通过将聚亚烷基,平均分子量为148〜5,000的聚醚胺与二环氧化物和/或聚环氧化合物反应生成的环氧化合物的新型硬化剂,与单环氧化合物反应后可能残留的氢原子的比例 并与氮气结合并且能够与环氧化物反应,到环氧化合物或聚环氧化合物的环氧基团在1:1.4至6的范围内,并且该初步产物与伯胺或仲胺的反应,所用的胺或 胺混合物的用量使得能够与连接到氮的氢原子反应的环氧化物基团的比例为1:2至10。
