ABSTRACT:
Nonionic and anionic water-soluble addition copolymers of acrylamide and N-substituted acrylamides are useful as flow modifiers in and as adsorbates from aqueous systems, particularly multiphase systems. The copolymers have a weight average molecular weight greater than 30,000 and are useful for many purposes including as thickening agents or rheology modifiers for water based systems, block improvement additives in water based coating formulations, and transfer aids in water based ink or roll coater formulations.
