Abstract: FLEXIBLE ELASTOMERIC THERMOPLASTIC POLYURETHANES, PROCESS FOR THEIR PREPARATION AND THEIR USE Soft, flexible elastic, thermoplastic polyurethanes contain as plasticizers phthalic acid bis(methoxyethyl ester), tricresyl phosphate, diphenylcresyl phosphate, and polyester polyurethanes having molecular weights from 4000 to 10,000 based on 1,4'-butanediol adipate and 4,4'diphenylmethane diisocyanate, generally in amounts from 1 to 50 weight percent. The plasticizers can be incorporated into the starting components used for preparing the polyurethane, into the reactable polyurethane mixture during preparation, or, preferably, into the resulting thermo plastic polyurethanes. The products are suitable for preparing sheets and molded parts, for example, pipes/tubing and profiles, and preferably for sealing profiles.

Abstract: Antistatic and/or electrically conductive thermoplastic polyurethanes contain carbon black whose surface area determined by the BET method is from 600 to 1200 m2/g, have a dibutylphtalate absorption number of 300 to 450 cm3/100 g/ a pour density of less than 250 kg/m3, and an average particle size less than 50 nm, are suitable for preparing films for flat heating elements, antistatic hoses, cables, and profiles. Incorporation of the carbon black into the thermoplastic polyurethane produced by the continuous sheet method takes place at temperatures under the primary melt peak for the crystalline rigid segments, measured by means of differential calorimetry, preferably in an extruder.

Abstract: EASILY DEMOLDABLE AND NON-BLOCKING THERMOPLASTIC POLYURETHANE ELASTOMERS, PROCESS FOR THEIR PREPARATION AND USE Easily demoldable and non-blocking thermoplastic polyurethane elastomer composition, obtained by melting: (A) from 50 parts to 99.5 parts by weight of a thermoplastic polyurethane elastomer with a urethane group content of from 10 50 percent by weight and a melt index of from 0.1 to 100 at 190.degree.C, with (B) from 0.5 part to 50 parts by weight of a thermoplastic polyurethane elastomer with a urethane group content of from 20 to 60 percent by weight and a melt index of 10 to 1000 at 190.degree.C, wherein the urethane group content of polyurethane elastomer (B) is always at least 10 percent by weight greater than that of (A) and the melt index of the polyurethane elastomer (B) is greater than or equal to that of (A) at the melt temperature. The elastomers are obtained by melting together the (A) and (B) polyurethane elastomers at temperatures from 140.degree.C to 250.degree.C, preferably in an extruder, with subsequent granulation.

Abstract: Filaments and fibers based on polypropylene or copolymers thereof having a content of from 10 to 90% by weight of bitumen and a process for their manufacture, in which a mixture based on polypropylene or copolymers thereof and containing from 10 to 90% by weight of bitumen is melt-spun and drawn. The filaments and fibers produced in the manner of the invention are suitable for the production of woven and non-woven fabrics for insulating purposes and carpet underlays.

Abstract: Unsaturated carboxylic acids are grafted onto copolymers of ethylene and carboxylates. Carboxylic acid containing initiator is caused to diffuse into shaped elements of the copolymers, polymerization then being carried to completion by heating. The products exhibit no fish eyes and are highly suitable for sheet manufacture.
