Vinyl polymerisation. VII. Polymerisation of acrylamide photoinitiated by anthraquinone sulphonates

Abstract

A systematic study of the kinetics of photo-chemical polymerisation of acrylamide using the system anthraquinone sulphonate-NaCl-HClO₄ under deaerated condition in aqueous solution has been done. The determinations of the monomer disappearance (bromometry), the sensitiser disappearance (spectrophotometry) and chainlengths of polymers with respect to light intensity, concentration of monomer, light absorption fraction (k_e) of sensitiser, etc., have been carried out. An overall kinetic mechanism is given in the light of experimental results.
