ABSTRACT:
Graft copolymers of cellulose derivatives and N,N-diallyl,N-N-dialkyl ammonium chlorides or bromides are prepared using a dry or substantially solvent-free system by impregnating a concentrated aqueous solution of the N,N-diallyl-N,N-dialkyl ammonium halide, water soluble surfactant and catalyst onto the dry cellulose substrate, heating the reaction mass for sufficient time to achieve polymerization and then drying.
