ABSTRACT:
Quaternary carboxamide polymers such as N-(triethylammonium ethyl)acrylamide chloride are prepared by simultaneously contacting a carboxamide polymer with an aldehyde such as formaldehyde, a secondary amine such as dimethylamine and a quaternizing agent such as methyl chloride. By such method, quaternary carboxamide polymers useful in a variety of applications such as emulsion breaking and water clarification are readily prepared.
