    • PROBLEM TO BE SOLVED: To provide a cationic resin aqueous solution which has a small content of a low-molecular organic halogen compound, or which is judged negative in the judgement of Ames test, and which is useful as a wet paper-strengthening agent.
      SOLUTION: The cationic resin aqueous solution is obtained by reacting a poly(N-alkyldiallylamine)-acid adduct with an epihalohydrin, further reacting an inorganic acid with the product, and converting the epoxy group into a halohydrin group, and has
    • 待解决的问题:为了提供低分子有机卤素化合物的含量少的阳离子性树脂水溶液,或者在Ames试验的判断中判断为阴性的阳离子树脂水溶液, 强化剂。 解决方案:阳离子树脂水溶液通过聚(N-烷基二烯丙基胺) - 酸加合物与表卤代醇反应获得,进一步使无机酸与产物反应,并将环氧基转化为卤代醇基团, 在阳离子树脂水溶液的固体成分的20%中DCP含量为1%。 使用通过使树脂水溶液与基材反应而获得的树脂获得的纸通过以下等式计算:≥15%的湿拉伸强度保持率(根据JIS P-8135测定)[湿拉伸强度保持率(% )] = [湿拉伸强度(kN / m)] / [干拉伸强度(kN / m)]×100。 版权所有(C)2009,JPO&INPIT
