The free radical dispersion polymerization of styrene (St) and methyl methacrylate (MMA) initiated by poly(oxyethylene) (PEO) macroazoinimer (MIM-400) in water/ethanol, was investigated at three different temperatures (50, 60 and 80 8C) for seven polymerization times (3, 6, 9, 12, 24, 36 and 48 h).
## Abstract Methyl methacrylate (MMA) was polymerized by thiophenol without oxidants. Hydroquinone had no effect on the polymerization, indicating that the polymerization proceeded via a non‐radical process. Since other monomers with an __x__,β‐unsaturated carbonyl group polymerized similarly, the
