Preparation of Micron-sized Styrenic Particle Dispersions, and Polyamide 6 Composites thereof

In this study, the cross-linked polystyrene (PS) polymer particles were synthesized by dispersion polymerization of styrene using azobisisobutyronitrile(AIBN) and polyvinylpyrrolidone(PVP) as initiator, and stabilizer respectively, in ethanol medium at 70°C temperature. They were then blended with Polyamide 6 in formic acid solution, and the final composite was prepared via casting. Microscopic evaluation showed a very good dispersion of particles in PA6 matrix which was attributed to the compatiblizing effect of PVP.
