    • A process for the production of water-soluble auxiliary agents based on polyaminoamides by reacting a polyfunctional compound with a tertiary, monofunctional amine to form an ammonium compound and reacting that ammonium compound with a basic polyaminoamide, the basic polyaminoamide being the polycondensation product of a dicarboxylic acid, a polyalkylenepolyamine and an aminocarboxylic acid or lactam thereof, the basic polyaminoamide being reacted with 0.15 to 0.19 mol of a polyfunctional compound per mol equivalent of secondary amino group in the polyamide, incorporating that modified basic polyaminoamide in the paper pulp so as to increase the retention of fibres, fillers or pigments, or to accelerate the drawings.
    • 一种通过使多官能化合物与叔单官能胺反应形成铵化合物并使铵化合物与碱性聚氨基酰胺反应的基于聚氨基酰胺生产水溶性助剂的方法,所述碱性聚氨基酰胺是二羧酸的缩聚产物 酸,聚亚烷基多胺和氨基羧酸或其内酰胺,碱性聚氨基酰胺与聚酰胺中相对于每摩尔当量仲氨基的0.15〜0.19摩尔多官能化合物反应,在纸浆中加入改性碱性聚氨基酰胺,以增加 保留纤维,填料或颜料,或加速图纸。
