ABSTRACT:
A process for combining a polythiol reactant and an alkenyl silane reactant to form a polysulfide polysilane. The reactants are combined in a thiol-ene addition process driven by UV radiation. The polysulfide polysilane is then hydrolyzed and may be combined with other hydrolyzed compounds. For coatings, the polysulfide polysilane is hydrolyzed and may optionally be combined with nanoparticles. For bulk materials, the polysulfide polysilane is hydrolyzed, concentrated, and heated to form a high refractive index material which can be used to form optical articles such as lenses.
