具有梳状稳定剂的水溶性聚合物的水分散体
摘要：
本发明涉及一种N－乙烯基羧酰胺的水溶性聚合物的水分散体，其中所述水分散体基本不含盐且包含具有梳状分子结构的阴离子聚合物稳定剂，本发明还涉及在具有梳状分子结构的阴离子聚合物稳定剂存在下制备该分散体的方法以及该分散体在造纸中作为助留剂或固定剂的用途。
摘要（英）：

The invention relates to aqueous dispersions of water-soluble polymers of N-vinyl-carboxamides, which are substantially salt-free and comprise anionic polymeric stabilizers having a comb-like molecular structure, processes for the preparation of the dispersions in the presence of anionic polymeric stabilizers having a comb-like molecular structure and the use of the dispersions as retention aids or fixing agents in papermaking.
