Abstract
Abstract The present invention provides a water-curable resin composition for use in the preparation of composite materials. The resin composition is composed of a water-reactive liquid organometallic compound having a viscosity of no greater than about 500,000 centipoise under ambient conditions; and a nonreactive organic thermoplastic polymer, having a number average molecular weight of at least about 1,000, mixed with the water-reactive liquid organometallic compound. Preferably, the water-reactive liquid organometallic compound is a compound of the formula (R 1 O) x MR 2 .sub.(y-x) wherein: each R 1 is independently a substituted or unsubstituted C 1 -C 100 hydrocarbon group, optionally interrupted in the backbone by 1--10 nonperoxide--O--, --S--, --C(O)--, or --N-- groups; each R 2 is independently selected from the group consisting of hydrogen and a substituted or unsubstituted C 1 -C 100 hydrocarbon group, optionally interrupted in the backbone by 1--10 nonperoxide--O--, --S--, --C(O)--, or --N-- groups; x is an integer between 1 and y, inclusive; y is the valence of M; and M is boron, aluminum, silicon, or titanium.
