Abstract : The project goals are to investigate the use of unsaturated carbosilanes function alized with a Si-Cl bond in the synthesis of solvent resistant elastomers and high performance polymers. We have successfully synthesized a variety of chlorofunction alized carbosilane polymers which are highly elastic materials. Substitution on this highly elastic backbone with nucleophiles provided materials which were virtually insoluble in every solvent system studied. These solvent resistant materials have shown good thermal stability, being resistant to decomposition in air up to 400 degrees centigrade.
