Abstract: A process for the preparation of cellular, microcellular and noncellular polyurethane polyurea molded parts involves the reaction of organic polyisocyanates, polyols having at least 2 reactive hydrogen atoms, and a chain extender containing at least 70 percent by weight of a mixture of aromatic diamines. These diamines comprise from 80 to 50 weight percent of at least one primary aromatic diamine whose amino groups are sterically hindered relative to reaction with polyisocyanates, and 20 to 50 weight percent of at least one unsubstituted or substituted reactive primary aromatic diamine whose amino groups do not exhibit reduced reactivity to polyisocyanates. The thus produced polyurethane polyurea polymers have excellent demoldability avoiding the use of external mold release agents.

Abstract: PROCESS FOR ENCAPSULATING GLASS EDGES WITH AN ELASTIC POLYISOCYANATE ADDITION POLYMERIZATION PRODUCT USING AN EPOXY RESIN CURING SYSTEM AS THE ADHESION-IMPROVING AGENT The invention is a process for encapsulating glass edges with an elastic polyisocyanate addition polymerization product which comprises coating an edge of glass with an adhesion-improving agent comprising an organic epoxy resin and a hardener and thereafter covering the coated edges with a polyurethane, polyurethane-polyurea or polyurea elastomer. The adhesion-improving agent is a two-component system comprising at least one organic epoxy resin and at least one hardener, preferably a polyamine and/or polyamine adduct, optionally dissolved in an organic solvent. A glass plate is positioned in a mold, the mold closed and the cavity between the plate of glass and the mold is injected, using a one-shot RIM process, with a reactive mixture of organic polyisocyanates, higher molecular weight compounds having at least two reactive hydrogen atoms, chain extenders and/or crosslinking agents, catalysts, and optionally auxiliaries and/or additives. The reaction mixture is allowed to cure, and the plate glass is removed.
