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.

Suitable diprimary diols have a molecular weight of from 90 to 800 and a structure at both hydroxyl groups corresponding to the general formula: ##STR1## in which R.sub.1 represents chlorine, an alkyl, cycloalkyl, aralkyl or aryl radical having from 1 to 10 carbon atoms, which carbon atoms may be substituted or interrupted by chlorine, ester groups, ether groups, amide groups, urethane groups or nitrile groups, andR.sub.2 represents hydrogen or a radical within the definition of R.sub.1.Polyethers which may be employed have at least two hydroxyl groups (at least 80% of which are secondary hydroxyl groups) and an average molecular weight of from 500 to 12,000. The disclosed solutions are particularly useful in the production of flexible polyurethane plastics which are suitable for flamecoating and high frequency bonding.
