The invention provides articles made of thermoplastic polyurethane based on polycarbonate diol which are a constituent of a device that receives or transmits electromagnetic radiation, are a cover for a device, or are used in proximity to such a device. The invention further provides for the use of thermoplastic polyurethane based on polycarbonate diol for these articles.

Polyurethanes with good permeability to electromagnetic radiation

The present invention relates to compositions comprising at least one thermoplastic polyurethane and at least one poly(meth)acrylate, where the at least one thermoplastic polyurethane is a polyurethane based on hexamethylene 1,6-diisocyanate (HDI), on at least one diol, and on at least one chain extender, selected from the group consisting of ethylene 1,2-glycol, 1,2-propanediol, 1,3-propanediol, 1,4-butanediol, 2,3-butanediol, 1,5-pentanediol, 1,6-hexanediol, diethylene glycol, dipropylene glycol, 1,4-cyclohexanediol, 1,4-dimethanolcyclohexane, and neopentyl glycol. The present invention further relates to moldings comprising the compositions of the invention, and also to the use of the compositions of the invention for producing a foil and for coating a molding.

Thermoplastically processable transparent blends of thermoplastic polyurethane and poly(meth)acrylates

Mixture (1) comprising from 1 to 40% by weight of (A) thermoplastic polyurethane based on aliphatic isocyanate and from 60 to 99% by weight of (B) acrylonitrile-styrene-acrylate copolymer (ASA) and/or acrylonitrile-ethylene homo- or copolymer-styrene (AES) material, based in each case on the total weight of the mixture ().
