Thickening agents for aqueous systems are disclosed comprising water-soluble addition polymers of acrylamide and an N-substituted acrylamide in which the substituent is a hydrocarbyl group of at least 6 carbon atoms, or such a group attached to the nitrogen atom via a polyoxyalkylene chain. Preferred substituents are alkyl groups containing 6-36 carbon atoms. The polymers are useful thickening agents for aqueous systems, particularly multiphase systems such as aqueous emulsion polymers and aqueous pigment dispersions, and especially aqueous emulsion paints and aqueous printing inks.
本发明公开了用于水性体系的增稠剂,包括丙烯酰胺和 N-取代丙烯酰胺的水溶性加成聚合物,其中取代基为至少 6 个碳原子的烃基,或通过聚氧亚烷基链连接到氮原子的烃基。首选的取代基是含有 6-36 个碳原子的烷基。这种聚合物是水性体系的有用增稠剂,特别是多相体系,如水性乳液聚合物和水性颜料分散体,尤其是水性乳胶漆和水性印刷油墨。
