ABSTRACT The conversion of polymeric waste into useful, value added material is considered as an efficient method for management because the environmental issues caused by such materials. This work proposes a simple, cost‐effective strategy expanded polystyrene nanoparticles via nanoprecipitation. In this method, dissolved in suitable solvent example, tetrahydrofuran and to nonsolvent, water, precipitate diameter less than 500 nm. study also investigates influence various process parameters as, initial concentration polystyrene, speed stirring, water volume ratio type used nanoprecipitation, on size polydispersity precipitated PS nanoparticles. © 2015 Wiley Periodicals, Inc.
