Abstract	Semicontinuous heterophase polymerization was used to polymerize methyl methacrylate (MMA) with the reactive surfactant Hitenol BC10 (polyoxyethylene(10)alkylphenyl ether ammonium sulfate, HBC10) in the presence of ultrasound at 50 °C. The effects of HBC10 concentrations and the monomer addition rate (R $_{a}$) on kinetics, colloidal behavior, and molar masses were studied. Latexes with polymer content between 20 and 24 % were obtained. Particle size distributions (PSD) of latexes without HBC10 were bimodal, whereas those obtained in the presence of HBC10 were mono-modal in all cases. The average particle diameters (D $_{p}$) were in the range of 39–63 nm decreasing with the HBC10 concentration and increasing with R $_{a}$. Polymerization rates (R $_{p}$) were decreased, by increasing the HBC10 concentration, which was ascribed to chain transfer events to HBC10. It was also observed that R $_{p}$ increased with R $_{a}$; however, monomer-starved conditions were favored at lower R $_{a}$ values. Very high-average molecular weights were observed (1.63 × 10$^{6}$ ≤ M $_{w}$ ≤ 2.34 × 10$^{6}$ g/mol) which decreased when HBC10 concentration increased, and increased with R $_{a}$. The corresponding polydispersity indexes (M $_{w}$/M $_{n}$) were in the range of 1.55–2.30, showing relatively wide molar masses distributions. It was observed from differential scanning calorimetry that polymers with HBC10 presented two T $_{g}$ (123 and 178 °C) which was ascribed to HBC10 incorporated to PMMA chain, corroborated by $^{1}$H NMR.
