Abstract

Micron-sized, monodisperse, cross-linked, hollow polymer particles having transformable shapes were produced by seeded polymerization of (divinylbenzene/vinylbiphenyl/xylene)-swollen polystyrene particles prepared utilizing the dynamic swelling method. The influence of the shell strength, which was controlled by shell thickness, cross-linking density and solvent-release temperature, on shape transformation of the hollow particles between sphere and non-sphere, respectively, based on the absorbed and release of solvent was discussed in comparison with a theoretical pressure-buckling relationship.
