摘　　要：研究了一种支化型两性聚丙烯酰胺的制备方法及其在助留助滤系统中的应用。实验结果表明:支化型两性聚丙烯酰胺较线性两性聚丙烯酰胺有更好的单程留着率,所得纸张灰分更高,同时两性聚丙烯酰胺较单一离子性的聚丙烯酰胺有更好的抗杂离子干扰能力,能够更好地适应复杂的造纸系统。The preparation of a kind of branched amphoteric polyacrylamidc was studied as well as its application. The results show that amphoteric potyacrylamide with branches has better first pass retention rate than linear ampboteric polyacrylamide, higher ash content in paper web, which can be suitable for the complicated papermaking system because of the better anti-interference ability.
