In this thesis, firstly, we prepared the polystyrene nanocapsules by radiation induced miniemulsion polymerization and studied the effect of factors on the final morphology from the both thermodynamic and kinetic theory; then we prepared the magnetite/polystyrene composite spheres and hollow spheres and studied the some influence of factors. The main results obtained in this dissertation are described as follows:
1. Preparation of polymeric nanocapsules by radiation induced miniemulsion polymeriza...
