Synthesis of statistical networks from liquid polybutadiene—IV. Influence of crosslinking agent

The synthesis of statistical macromolecular networks is achieved from liquid polybutadiene as precursor polymer with difunctional crosslinking agents bearing two hydrogenosilane groups. The properties of the network (extractable polymer, equilibrium swelling degree, uniaxial compression modulus) are strongly influenced by the structure of the crosslinks. Aromatic type structures are best suited to obtain high modulus networks which can be used for applications in the field of composite materials.
