Abstract:
PCT No. PCT/EP91/01803 Sec. 371 Date Jul. 24, 1992 Sec. 102(e) Date Jul. 24, 1992 PCT Filed Sep. 21, 1991 PCT Pub. No. WO92/11305 PCT Pub. Date Jul. 9, 1992.A novel, particularly flexible, improved process for molding microcellular elastomer polyurethane articles comprises reacting a first type quasi-polyurethane, having a molecular weight of from 600 to 2200 and a free isocyanate group percent content of from 14 to 3.8, with at least one of a second type of quasi-polyurethane, having a molecular weight of from 3000 to 8000 and a free hydroxyl group percent content of from 1.13 to 0.48, and a glycol and optionally in the presence of water. The process according to the invention is particularly well-suited for automation by means of a processor. Also, the preparation of certain microcellular elastomer polyurethanes that are useful in the improved molding process is described.
