一般增干强剂在纸张增强的同时具有对浆料的助滤、助留作用，尤其是PA M增强剂，在日本获得广泛应用。然而，由于废纸回用的增加、白水封闭循环以及大量填料的添加，使得普通PA M的效果下降。基于此，本文介绍了研发的新型PA M增强剂，具有高分枝化、高分子量和新型结构，与普通PA M相比，增强、助滤、助留效果优异，能够满足近年来苛刻的抄纸环境，生产出优良的纸和纸板。
一般增榦彊劑在紙張增彊的同時具有對漿料的助濾、助留作用，尤其是PA M增彊劑，在日本穫得廣汎應用。然而，由于廢紙迴用的增加、白水封閉循環以及大量填料的添加，使得普通PA M的效果下降。基于此，本文介紹瞭研髮的新型PA M增彊劑，具有高分枝化、高分子量和新型結構，與普通PA M相比，增彊、助濾、助留效果優異，能夠滿足近年來苛刻的抄紙環境，生產齣優良的紙和紙闆。

Dry strength resin is known as multifunctional chemicals to enhance paper/paperboard strength, drainage and retention. Especially, polyacrylamide(PAM) based dry strength resin is used in various paper/paperboard grades in Japan, because of its great performance in dry strength enhancement, and controlling retention/drainage to reduce energy use for beating and dryer steam. But nowadays, performance of conventional PAM based dry strength resin has become unsatisfactory, because of the recent trends in papermaking industry toward the greater use of recycled pulp, progress for white water closed system and higher loading of ifllers. In this report, novel PAM based dry strength resin with highly-branched structure, higher molecular weight and novel component, were investigated to enhance the performance of PAM under recent papermaking conditions.
