Abstract: The invention relates to transparent, autoclavable, non-cytotoxic, essentially compact polyurethane embedding compositions which are prepared by reacting a) modified diphenylmethane diisocyanates with b) compounds with at least two reactive hydrogens, which contain or are composed of b1) at least one polyether-polyol with an average functionality of from 3 to 8, a hydroxyl number of from 200 to 1000 and an alkali metal ion content of from 150 to 1200 ppm or, preferably, a mixture of (b1) and castor oil and/or at least one polyetherpolyol (b2) with a functionality of from 2 to 3, a hydroxyl number of from 90 to 200 and an alkali metal ion content of less than 10 ppm in the presence or absence of c) catalysts and to a process for preparing the polyurethane embedding compositions and to the use thereof for articles used in medicine.

Abstract: REINFORCED CELLULAR OR NONCELLULAR POLYURETHANE MOLDED PARTS Reinforced cellular or noncellular molded polyurethane parts are prepared by heating a mixture of reinforcing materials and a heat-curable composition of polyisocyanates and polyols in an open or closed mold, said composition being storage-stable at room temperature and containing, optionally, auxiliaries and additives. In said composition, the polyisocyanate is dispersed in the form of discreet particles having particle diameters from 0.1 to 150 .mu.m in the polyol and the polyisocyanate particles are deactivated on their surfaces such that from 0.01 to 20 equivalent percent of the total available isocyanate groups are deactivated and such that the ratio of free isocyanate groups to hydroxyl groups is from 0.7:1 to 2.5:1. The polyurethane molded parts are suitable for use as self-supporting trim parts, reinforcement parts, or molded parts for various applications.

Abstract: Thermoplastic nylons are stabilized with copper compounds and synergistic halides by incorporation of from 0.1 to 10% of a concentrate of nylon, copper bromide or iodide and calcium bromide, zinc bromide or magnesium bromide. The stabilized nylons may be thermoplastically processed to give semimanufactures or films.

Abstract: A specific copolyamide and its use for finishing leather and leather substitutes, particularly those of polyurethane. A particular advantage of the copolyamide is its sealing effect counteracting the migration of dyes, plasticizers and fats, combined with other advantages such as good mechanical properties and the stability of the solutions.
