Abstract: A process for preparing a carbodiimide includes (i) providing a mixture including one or more isocyanates and a catalytic compound, and (ii) subjecting the mixture obtained in (i) to reaction conditions in a gas atmosphere. The catalytic compound includes a metal and oxygen, wherein the metal is one or more of Mo and W. and at least a portion of the metal in the catalytic compound is bound to oxygen via one or more single bonds, via one or more double bonds, or via one or more single and double bonds. The reaction conditions in the gas atmosphere take place at a temperature in a range of from 45 to 220° C.

Abstract: A method is described for debonding a bonded article. The bonded article comprises at least two components which are bonded to one another by means of a polyurethane adhesive selected from aqueous polyurethane dispersion adhesives and polyurethane hotmelt adhesives. At least one of the components is a thermoplastic polyurethane. The components are debonded by treatment with an aqueous surfactant composition at elevated temperatures.

Abstract: The present invention relates to chemical compounds which can be used in particular as structural mimetics of proline-rich peptides. The compounds of the present invention are capable of selectively inhibiting Ena/VASP-EVH1-mediated protein-protein interactions. The invention further relates to the use of these compounds as pharmaceutical agents and the use of the pharmaceutical agents for the treatment of tumor diseases.

Abstract: The present invention relates to a sinter powder (SP) comprising 58.5% to 99.95% by weight of at least one thermoplastic polyurethane (A), 0.05% to 1.5% by weight of at least one flow agent (B), 0% to 5% by weight of at least one organic additive (C), 0% to 5% by weight of at least one further additive (D) and 0% to 30% by weight of at least one reinforcer (E), based in each case on the sum total of the percentages by weight (A), (B), (C), (D) and (E), wherein the thermoplastic polyurethane (A) is prepared by reacting at least one isocyanate (a), at least one isocyanate-reactive compound (b), and at least one chain extender (c), and wherein components (a), (b) and (c) each comprise not more than 15 mol-% of aromatic moieties, based on the total amount of the respective component (a), (b) and (c). The present invention further relates to a method of producing the sinter powder (SP) and to the use of the sinter powder (SP) in a three-dimensional (3D) printing process.

Abstract: A thermoplastic polyurethane (TPU) with high transparency and improved stain resistance is made. The process for producing a shaped body out of such a thermoplastic polyurethane is developed for consumer applications.

Abstract: A process can be used for the preparation of a carbodiimide and/or a polycarbodiimide, where the process is particularly essentially free of an alkali metal. The carbodiimide and/or polycarbodiimide obtained and/or obtainable by the process and uses thereof are also provided.

Abstract: A thermoplastic polyurethane is a reaction product obtained from components including (A) an aliphatic polyisocyanate, (B) an aliphatic polyol having at least one side chain, and (C) chain extenders. The aliphatic polyol (B) is a polycarbonate diol of formula (I): In formula (I), n is 4 to 40, and n+1 Rs are composed of a linear alkylene and an alkylene having at least one side chain so as to have the molar ratio of the linear alkylene to the alkylene having at least one side chain in the range of 0:100 to 95:5. The chain extender (C) is a combination of 1,4-butanediol with 1,3-propanediol, 1,5-pentanediol, 3-methyl-1,5-pentanediol, or ethylene glycol, and the amount of 1,4-butanediol is 50% by mass or more based on the total amount of the chain extenders (C). A resin composition containing the thermoplastic polyurethane and a corresponding molded product are also provided.
