Abstract

The present disclosure relates to a composition and a method to prepare a polymer nanoparticle using miniemulsion polymerization (MEP) comprising a monomer, a reactive co-stabilizer and a reactive surfactant. The reactive co-stabilizer as disclosed is a methacrylate containing perfluorinated or semifluorinated side chains like 1H,1H,2H,2H-perfluorodecyl methacrylate (H2F8MA). Further, the reactive stabilizer as used in the preparation is cetyl trimethyl ammonium chloride (CTAB). The polymer nanoparticle as formed has an enhanced stability and low VOC as compared to a pure polymer prepared by MEP.
