Patent ID: 8058347

Claim:
A method for making a composite comprising: a first heating of a first mixture comprising: i) a metal alkoxide 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 substituted or unsubstituted, saturated or unsaturated, hydrocarbyl group having from 1 to about 10 carbon atoms, OR 1 is each independently an alcoholyzable hydrocarbyloxy group having from 1 to about 10 carbon atoms, x is 0 to 5, and m is 1 to 5, and ii) a diol of the formula HOâ€”R 2 â€”OH, an alcohol of the formula HOâ€”R 3 , or a mixture thereof, where R 2 is a divalent substituted or unsubstituted hydrocarbylene having from 1 to about 10 carbon atoms, or an oligomeric or polymeric group comprising at least one chain incorporating a plurality of alkoxyl groups, urethane groups, carbonate groups, or a combination thereof; R 3 is an unsaturated and polymerizable hydrocarbyl having from 3 to about 18 carbon atoms; and combining a monomer having at least one unsaturated isocyanate or a polymerizable oligomer having at least one isocyanate, a cross-linker, and a free radical initiator, and the product of the heated first mixture, and performing a second heating to form the composite.
