摘要:

The aqueous polymerization of acrylonitrile (AN) initiated by the potassium persulfate-thiomalic acid (TMA) redox system has been studied at 35 ± 0.1°C in a nitrogen atmosphere. The rate of polymerization is governed by the expression, Rp= K[AN] [S2O82-]x[TMA]0.40, where x = 0.60 for lower monomer concentration md 0.75 for higher monomer concentration. The overall activation energy was found to be 7.3 kcal/mol in the investigated range of temperature. The deviations from normal kinetics are discussed, and a tentative mechanism of initiation is given. The effects of inorganic electrolytes on polymerization were also investigated.
