Abstract
Resins and carbon-carbon composites are formed from di(alken-1-yl) borinic acids and borinates, either as monomers or as nonpolymerizing additives in a monomer mixture, with the effect of sharply increasing the oxidative stability of the cured product. The compounds have the formula ##STR1## in which R1, R2, R3, R4 and R5 are H, C1 -C6 alkyl, C2 -C6 alkenyl, C2 -C6 alkynyl, C3 -C7 cycloalkyl, C5 -C7 cycloalkenyl, aryl, (C1 -C6 alkyl)-substituted aryl, (C2 -C6 alkenyl)-substituted aryl, or (C2 -C6 alkynyl)-substituted aryl, at least one of R1, R2, R3, R4 and R5 being other than H.
