ABSTRACT:
This invention relates to adducts of salts of polymerizable tertiary amines with acrylic compounds illustrated by acrylamide and acrylonitrile; to polymers and copolymers containing said adducts and to processes for preparing them. This invention also relates to the use of said polymers and copolymers, particularly in the clarification of turbid waters by flocculation or flotation of oil and/or suspended solids. In the preferred embodiment, the quaternary adduct monomer is: ##STR1## where X is an anion, preferably halide such as chloride or carboxylate such as acetate; and polymers and copolymers containing units thereof.
