摘要：An improved polyurethane is prepared by reacting a diol component and anorganic diisocyanate with critical selection of the amount of water in the reaction mixtureand the diol component. The diol component is a long chain polyoxyethylene glycoloptionally mixed with a low molecular weight polyoxyethylene glycol. A tough gel can beformed by mixing the polyurethane in a diol or triol and water solution. The tough gelcan be used in burn and wound dressings, electroconductive pads, high slip materials andsurgical implants. An optically clear gel can also be formed. Solutions and emulsions canbe formed of the polymer and can be combined with fillers to form face creams andantiperspirants. A film can cover one side of the gel for burn and wound applications. Thegel can be used in squeeze tubes and in spray cans in burn wound care dressings andindustrial applications and in bags and containers for use in plastic surgery implants.
