Synthesis of core–shell polymer particles in supercritical carbon dioxide via iterative monomer addition

Abstract

A new, robust methodology for the synthesis of polystyrene–poly(methyl methacrylate) (PS–PMMA) core–shell particles using seeded dispersion polymerisation in supercritical carbon dioxide is reported, where the core–shell ratio can be controlled predictably via manipulation of reagent stoichiometry. The key development is the application of an iterative addition of the MMA shell monomer to the pre-prepared PS core. Analysis of the materials with differing core–shell ratios indicates that all are isolated as single particle populations with distinct and controllable core–shell morphologies.
