Notes:
The micellar effect on the kinetics of ceric ion-initiated polymerization of acrylonitrile (AN) in the presence of glucose was studied in the temperature range 40-50°C. The effects of concentration of the metal ion, monomer, sulfuric acid, substrate (glucose), emulsifier, some inorganic salt, and organic solvent on the rate of polymerization (Rp) were also investigated. The remarkable features of the investigation involve the enhancement of Rp in the presence of a micelle, the derivation of the rate expression for the above system along with the calculation of activation energy, and prediction of optimum conditions. Comparison of the rates for a micellar medium with those for the aqueous medium indicates that cationic micelles exert an accelerating influence on the rates of polymerization. © 1995 John Wiley & Sons, Inc.
