Polymerization of styrene in microemulsion was carried out using an oil-in-water system and sodium dodecylsulphate surfactant. The oil/surfactant ratio was observed to be 1 : 1.8 at 30°C. However, systems containing more than 5% w/w styrene in microemulsion turned into emulsion. Use of styrene - 2-hydroxyethyImethacrylate (2-HEMA) mixture could overcome this problem where 2-HEMA acts as polymerizable cosurfactant. Various conditions such as type and concentration of initiatiors, temperature were optimized for polymerization of styrene using SDS and 2-HEMA as surfactant and cosurfactant respectively. The products synthesised at optimized conditions were characterized by IR, NMR and dynamic light scattering. The rate of polymerization was also calculated.

Abstract


Polymerization of styrene in microemulsion was carried out using an oil-in-water system and sodium dodecylsulphate surfactant. The oil/surfactant ratio was observed to be 1 : 1.8 at 30°C. However, systems containing more than 5% w/w styrene in microemulsion turned into emulsion. Use of styrene - 2-hydroxyethyImethacrylate (2-HEMA) mixture could overcome this problem where 2-HEMA acts as polymerizable cosurfactant. Various conditions such as type and concentration of initiatiors, temperature were optimized for polymerization of styrene using SDS and 2-HEMA as surfactant and cosurfactant respectively. The products synthesised at optimized conditions were characterized by IR, NMR and dynamic light scattering. The rate of polymerization was also calculated.
