Notes:
The micellar effect on the kinetics of ceric ion-initiated polymerization of acrylonitrile (AN) in the presence of N-acetylglycine has been studied in the temperature range 30-50°C. The neutral emulsifier (Triton X-100) has no effect on the Rp, whereas both anionic (NaLS) and cationic (NCTAB) emulsifiers accelerate the rate of polymerization appreciably. Comparison of the effect of different organic substrates on the rate of polymerization has been made. Various effects such as the concentration of metal ion, surfactant, monomer, sulfuric acid, organic solvents, and inorganic salts on Rp have also been investigated. The most remarkable feature of the investigation involves the enhancement of Rp in the presence of micelles. A suitable mechanism for the derivation of the rate expression for the above system is proposed along with the calculation of activation energy and prediction of optimum conditions. © 1994 John Wiley & Sons, Inc.
