Abstract
The present invention provides a water-curable resin composition for use in an orthopedic cast composed of a water-reactive liquid organometallic compound having at least one hydrolyzable group per molecule and a viscosity of no greater than about 100,000 centipoise under ambient conditions; and an organic polymer, having a number average molecular weight of at least about 400, mixed with the water-reactive liquid organometallic compound. Preferably, the water-reactive liquid organometallic compound is a compound of the formula (R.sup.1 O).sub.x MR.sup.2.sub.(y-x) wherein: each R.sup.1 is independently a substituted or unsubstituted C.sub.1 -C.sub.100 hydrocarbon group, optionally interrupted in the backbone by 1-50 nonperoxide --O--, --S--, --C(O)--, or --N-- groups; each R.sup.2 is independently selected from the group consisting of hydrogen and a substituted or unsubstituted C.sub.1 -C.sub.100 hydrocarbon group, optionally interrupted in the backbone by 1-50 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.
