Polymerization of methyl methacrylate (MMA) was carried out in aqueous sulfuric acid medium at 3OoC using ammonium ceric sulfate (ACS)/methyl ethyl ketone ( M E K ) and ammonium ceric sulfate/acetone as redox initiator systems. A short induction period was observed with both the initiator systems, a
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) emuls
