摘要： Provided is a separator for non-aqueous batteries, capable of being usefully used in non-aqueous batteries, and a non-aqueous battery equipped with this separator. The separator for non-aqueous batteries includes: a base layer comprising a fiber aggregate, and an electrolyte-swellable resin layer formed on at least one surface of the base layer, the resin layer comprising a urethane resin (C) obtained by reacting a polyol (A) including a vinyl polymer (a1) and a polyether polyol (a2) with a polyisocyanate (B). The vinyl polymer (a1) has as a main chain a vinyl polymer (a1') having two hydroxyl groups at one of the termini of the main chain, and a polyoxyethylene chain having a number average molecular weight of 200 to 800 as a side chain, the percentage of the polyoxyethylene chain based on the vinyl polymer (a1) being within the range of 70 mass% to 98 mass%.

摘要： The invention provides a process for producing an alcohol-soluble urethane resin composition which is excellent in storage stability in an alcohol but which by adding water and a catalyst to the system during use, coating the mixture and drying the coating at ordinary temperature or by heating to allow a crosslinking reaction to proceed, thereby forming a film, is capable of obtaining excellent characteristics required for applications when used for, for example, synthetic leathers or artificial leathers, polyurethane porous bodies, moisture-permeable films and the like, such as solvent resistance (for example, alcohol resistance), chemical resistance (for example, DMF resistance), heat resistance, elongation and the like. Also, the invention provides a polyurethane porous body or a moisture-permeable film using a urethane resin composition obtained by the foregoing production process.
