Effect of Temperature on Emulsion Polymerization of n-Butyl Acrylate

Poly (n-butyl acrylate) was synthesized by emulsion polymerization using CHP-Ferrous sulfate redox system asinitiator. The effect of reaction temperature on the polymerization rate and particle size (D) was studied. The reaction showed a relatively high rate and reached high conversion in short time. The particle size was dependent on the reaction temperature. The size of particle reduced from 95 nm to 65 nm when the reaction temperature changed from 20 °C to 70 °C with fixed polymerization conditions. The activation energy is 29.80 kJ/mol.
