More Information
Summary:The invention relates to a process for the preparation of elastic, noncellular or cellular polyurethane molded articles or polyurethane-polyurea molded articles through reactions of (a) an organic polyisocyanate, (b) a polyester polyol having a hydroxyl number of from about 25 to 100 and an acid number of less than 2, prepared through the polycondensation of organic dicarboxylic acids with at least one polyoxytetramethylene glycol having a molecular weight of from about 162 to 600, or a mixture comprised of the said polyoxytetramethylene glycols with aliphatic diols and/or polyoxyalkylene glycols having a molecular weight of from about 106 to 1000, (c) a chain extending agent in the presence of (d) a catalyst and, optionally, (e) a blowing agent, (f) an auxiliary agent and/or additive.
