Inertial Confinement Fusion experiments are conducted in polymer capsule in which nuclear products are located. The polymer capsule is based on polystyrene polymer and are obtained by using a triphasic emulsion process. The capsule characteristics mainly depend on the number average molecular weight, the molecular weight dispersity and finally the atomic composition. It has been shown that the surface quality of capsule is directly connected to the polydispersity index. The best results have been obtained by using polystyrene which exhibited polydispersity index inferior to 1.20. The aim of this study is to develop organometallic polymers by using living radical controlled polymerization process in order to control physical properties and final composition.
