Abstract: An oxidation resistant fiber-reinforced composite is made by impregnating a fibrous material with a resin containing a linear polymer having a repeating unit with at least one carboranyl group, at least one silyl or siloxyl group and at least one acetylenic group. The linear polymer may then be cured to form a fiber-reinforced thermoset or may be pyrolyzed to form a fiber-reinforced ceramic. For additional protection of the fibrous material against oxidation, the fibrous material may be prewetted or coated, also with a linear polymer containing a linear polymer having a repeating unit with at least one carboranyl group, at least one silyl or siloxyl group and at least one acetylenic group, prior to being impregnated. The coating on the fibrous material may be cured to form a thermoset coating on the fibers or may be pyrolyzed to form a ceramic coating on the fibers.

Abstract: An improved method of synthesizing bisorthodinitriles having the formula: ##STR1## where R is an aliphatic or aromatic radical, which involves dissolving theeactants in a dipolar aprotic solvent such as dimethylformamide, and heating the mixture to reflux until the completion of the reaction. The usage of such solvents permits the reaction to be completed at least ten times as fast as the prior-art method, while the volume of solvent used is also reduced by a factor of ten.
