Patent ID: 7939687

Claim:
A method for making a composite comprising: a first reacting of a mixture comprised of: i) an alkoxide compound of the formula R x M(OR 1 ) m-x , where M is Si, Ti, Ta, Sn, Al, Zr, Hf, or a combination thereof, R, if present, is a hydrocarbyl group having from 1 to about 10 carbon atoms, or an unsaturated hydrocarbyl group having from 1 to about 10 carbon atoms, OR 1 is each independently an alcoholysable hydrocarbyloxy group having from 1 to about 10 carbon atoms, x is 0 to 4, and m is 1 to 5, and ii) a diol of the formula HO—R 2 —OH, or an alcohol of the formula HO—R 3 , where R 2 is a divalent hydrocarbyl group having from 1 to about 10 carbon atoms, or a polymeric group; R 3 is a polymerizable unsaturated hydrocarbylene group having from 3 to about 18 carbon atoms, or a mixture of a diol of the formula HO—R 2 —OH and an alcohol of the formula HO—R 3 ; and a second reacting of a mixture comprising the resulting product of the first reacting and a mixture comprised of an unsaturated anhydride, a cross-linker, and a free-radical initiator.
