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