ABSTRACT:
New copolymers have been made by reacting a divinyl aromatic compound, e.g., divinyl benzene, with primary or secondary amines, e.g., alkylene diamines or aromatic amines in the presence of a non-hydroxyl strong base, e.g., sodium amide. The reaction may be conducted neat or in an aprotic solvent such as tetrahydrofuran at ambient temperature.
The copolymers may be quaternized with alkyl and aralkyl chlorides to give products which are useful algaecides and bactericides. The copolymers themselves can be used in detergents since they have surfactant properties.
