Beschreibung
Zusammenfassung:	The invention concerns a high-frequency weldable and low-temperature flexible polymer mixture containing a copolymer of ethylene with a polar comonomer selected from the group of vinyl esters of saturated C2-C8 carboxylic acids, C1-C12 alkyl acrylates, and/or methacrylates, with the comonomer content being less than approximately 25% by weight, a terpolymer and/or copolymer of ethylene, propylene, and/or butylene, and a polar comonomer, with the comonomer content being less than approximately 25% by weight, and a thermoplastic polyolefin. The invention also provides a sheet or a molded piece containing the polymer mixture according to the invention and use thereof. Articles made with the polymer exhibit a high degree of low-temperature flexibility and favorable thermal stability together with sufficient high-frequency weldability and favorable welding seam strength.
