The copolymerization of acrylonitrile with unsaturated derivatives of hydrazion‐s‐triazine

Substituted hydrazino‐s‐triazines have been synthesized as intermediates by two methods and their benzal derivatives prepared. A possible mechanism for the formation of hydrazino‐s‐triazines is proposed. Two new monomers, 2,4‐dimethoxy‐6‐(β‐itaconylhydrazino)‐s‐triazine and 2,6‐diphenoxy‐6‐(β‐itaconylhydrazino)‐sytriazine, prepared from these intermediates were copolymerized with acrylonitrile and the monomer reactivity ratios were determined. The copolymers were found to be readily dyeable with methylene blue.
