Synthesize of Golf ball-like polymer particles: effect of monomer and solvent content on shape

Due to their inherent tendency to minimize the interfacial energy, polymer particles are normally spherical. However, non -spherical polymer particles have attracted the attention of scientific community in various applications like biotechnology, light scattering, and medicine. There are different methods for production of non-spherical particles. The seeded dispersion polymerization, in which particle size and distribution are controllable, is the favorite method for synthesis of the non-spherical polymer particles.By using this method, the particles with various shapes such as strawberry-like, golf ball-like, and disk-like ones have been synthesized. In this work composite golf ball-like polymer particles were prepared via seeded dispersion polymerization of 2- ethyl hexyl methacrylate on polystyrene seed particles (2.7 μm in diameter) in the presence of an organic solvent in ethanol/water medium. Among the most important polymerization parameters determining the shape and size of golf ball-like polymer particles, the effect of monomer and solvent content was studied in detail
