    • 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.
    • 本发明提供一种用于整形外科植入物的水硬化性树脂组合物,其由每分子具有至少一个可水解基团的水反应性液体有机金属化合物和环境条件下粘度不大于约100,000厘泊组成; 和数均分子量为至少约400的有机聚合物与水反应性液体有机金属化合物混合。 优选地,水反应性液体有机金属化合物是式(R1O)xRMR2(yx)的化合物,其中:每个R 1独立地是取代或未取代的C 1 -C 100烃基,任选地在骨架中被1-50个非过氧化物-O - , - S - , - C(O) - 或-N-基团; 每个R 2独立地选自氢和取代或未取代的C 1 -C 100烃基,任选地通过1-50个非过氧化物-O - , - S - , - C(O) - 或-N - 团体 x是1和y之间的整数,包括1和y; y是M的化合价; M是硼,铝,硅或钛。
