Cationic polyetheramine dispersants for preparing papermaking stock

A cationic polyether amine dispersant for papermaking fibers comprises the polymeric reaction product of a polyether diamine， a polyether bisepoxide and a quaternary ammonium salt. The polyether diamine， the polyether bisepoxide and the quaternary ammonium salt reactants are reacted in the following molar ratios: the molar ratio of amine functionality of the polyether diamine to epoxide functionality of the polyether bisepoxide is from 0.5:1 to 2:1 and the molar ratio of the amine functionality of the polyether diamine to the epoxide functionality of the quaternary ammonium salt is from 10:1 to 40:1. The dispersant is used in stock preparation used in paper products including absorbent products as well as paperboard.

一种用于造纸纤维的阳离子聚醚胺分散剂（cationic polyether amine dispersant），其包含聚醚二胺（polyether diamine）、聚醚双环氧化物（polyether bisepoxide）与季铵盐（quaternary ammonium salt）的聚合反应产物。上述三种反应物的摩尔配比满足如下要求：聚醚二胺的胺官能团与聚醚双环氧化物的环氧官能团的摩尔比介于0.5:1至2:1之间；聚醚二胺的胺官能团与季铵盐的环氧官能团的摩尔比介于10:1至40:1之间。该分散剂可应用于吸水制品及纸板等纸品的备料工序中。
