Summary

In the synthesis of coloured acrylonitrile copolymers, a coloured comonomer (a derivative of acrylamine), namely 2-acryloylamine-4-chloro-6-(8- hydroxy-3',6'-disulphonyl-7'-phenylazo-1'-naphthylamine)-1,3,5-triazine, was used. The effect of time, temperature, concentration of redox initiator, content of coloured comonomer in the reaction mixture, comonomer dosing rate and presence of salt (NaCl) in the system on the yield, composition and molecular weight (limiting viscosity number) of copolymers prepared in aqueous medium was investigated.
