    • The present invention relates to agents for increasing the retention of fibres, fillers and pigments and for accelerating drainage in papermaking, and as flocculating agents in the working up of effluents from papermaking by filtration, sedimentation and flotation. They are characterized in that they contain, as active components, one or more nitrogen-containing condensation products which can be obtained by reacting (A) aliphatic polyol-ether-amines which are free from halogen groups, contain cohesive polyether segments and carry no amino groups within these segments, with (B) compounds which are polyfunctional towards amino groups, optionally in the presence of (C) polyaminopolyamides and/or (D) polyalkylenepolyamines, component (B) being employed in an amount such that water-soluble polycondensates which have a viscosity of 100 to 1,000 mPa.s at 25.degree. C. in 25% strength aqueous solution are formed.
    • 本发明涉及用于增加纤维,填料和颜料的保留性并用于加速造纸中的排水的试剂,以及作为通过过滤,沉淀和浮选的造纸废水处理中的絮凝剂。 它们的特征在于它们含有作为活性组分的一种或多种含氮缩合产物,其可以通过使(A)不含卤素基团的脂族多元醇 - 醚 - 胺反应而得到,含有聚合链段并且不携带氨基 在(C)聚氨基多酰胺和(D)聚亚烷基多胺的存在下,(B)化合物对于氨基具有多官能团的化合物,组分(B)的使用量使得水溶性缩聚物 在25℃下在25%强度的水溶液中形成100至1,000mPa.s的粘度。
