Etude de la reaction d'addition de polystyrenes ω-vinylsilane avec une molecule-modele des α,ω-dihydrogeno-polydimethylsiloxanes

Three-block copolymers polystyrene-polydimethylsiloxane-polystyrene can be obtained by a hydrosilylation reaction between α,ω-dihydrogeno polydimethylsiloxane and ω-vinylsilane polystyrene molecules.The purpose of the present investigation was to establish by use of a model system, the optical conditions for the synthesis of three-block and multiblock copolymers: reaction temperature and concentrations of reactants and catalyst.
