Abstract

The synthesis of core-shell type polystyrene monodisperse particles with surface chloromethyl groups was carried out by a two-step emulsion polymerization process at different reaction temperatures. In a first step, the core was synthesized at 90 °C by means of batch emulsion polymerization of styrene (St), and in the second step, the shell was polymerized by batch emulsion copolymerization of St and chloromethylstyrene (CMS) using the seed obtained previously. With the aim of optimizing the production of these core-shell type polystyrene monodisperse particles with surface chloromethyl groups, the reaction temperature in the second step, the purification or not of the functionalized monomer (CMS), the amount and type of the redox initiator system used, and the type of addition of the initiator system to the reactor were studied.
