Abstract:

Toward the ojbective of synthesizing thermally stable elastomeric carborane-siloxane polymers, silane, carborane, and silane-carborane intermediates and monomers were prepared. Chlorosilanes, alkoxysilanes and a cyclic siloxane monomer were polymerized by heterogroup condensation, hydrolysis-condensation and ring-opening polymerization techniques. Polymers were obtained that ranged from viscous liquids and brittle solids to elastomeric gums depending on polymer molecular weight and structure. Author
