Abstract: In order to prepare thermoplastic polyurethane elastomers (a) organic diisocyanate, (b) polyhydroxyl compounds with molecular weights of 500 to 8,000, and (c) chain extenders with molecular weights of 60 to 400 in the presence of (d) catalysts, and optionally (e) auxiliaries, and/or (f) additives are reacted in two reaction stages at temperatures from 60 DEG C. to 250 DEG C. In the first reaction stage the components are continuously mixed, the reaction mixture is applied to a carrier, preferably a conveyor band of thermoplastic material, and is allowed to react at the reaction temperature until solidified. Subsequently, the solidified reaction mixture is melted in an extruder and the reaction is completed in the second reaction stage.

Abstract: The invention relates to a process for producing compact or cellular mouldings of polyurethane, polyurea or polyurethane-polyurea containing reinforcing agents by reacting a) organic polyisocyanates, b) compounds with molecular weights from 10,000 to 400 and at least two reactive hydrogen atoms and c) chain extenders and/or cross-linkers in the presence of d) fibre-containing reinforcing agents and, if appropriate, e) catalysts, f) blowing agents, g) auxiliaries and/or additives in closed moulds, the components (a) to (c) and, if appropriate (e) to (g) being processed as one-shot systems by the reaction injection moulding process and the fibre-containing reinforcing agents used comprising one or more polyurethane thermosets with a compressive strength (perpendicular to the plane of the mats) of 1.1 to 0.1 N/mm at 30 % compression, which contain, based on the total weight, 50 to 95 % by weight of a fibre-containing sheet-like structure.

Abstract: 1,228,976. Chlorinating polyethylene. BADISCHE ANILIN- & SODA-FABRIK A.G. 28 Aug., 1968 [29 Aug., 1967], No. 41122/68. Heading C3P. Polyethylene is chlorinated in a continuous process in which finely particled polyethylene is treated with chlorine in a chlorohydrocarbon whose boiling point is in the range from 30‹ to 90‹ C., the process comprising continuously introducing a high pressure polyethylene in the form of particles having a diameter of from 2 to 6 mm., a chlorohydrocarbon and chlorine into a reaction zone which contains solid polyethylene and a solution of from 1 to 20% by weight with respect to the solution of chlorinated polyethylene in the chlorohydrocarbon, continuously withdrawing from the reaction zone a fraction of the solution which is equivalent in amount to the amount of constituents being continuously introduced, and isolating chlorinated polyethylene from the solution withdrawn. Suitable chlorohydrocarbons are carbon tetrachloride, chloroform and trichloroethane.
