Abstract
1. An alloy of thermoplastic polyurethane (TPU) and polyolefin (PO), characterized by at least one of the following properties: the ratio of the surface tension of TPU to the surface tension of PO, measured at a temperature above the melting point of the alloy, is from 0.5 to 1.5; A PO contains at least one functional group that can provide long-range interactions with one or more TPU segments; the viscosity of the discrete phase compared to the viscosity of the matrix phase is below 2 under processing conditions. 2. The alloy according to claim 1, characterized in that the RO is selected from the group of polyethylene (PE), polypropylene (PP), a polyethylene copolymer and a polypropylene copolymer. 3. The alloy according to claim 1, characterized in that the PO are copolymers of monoolefins and diolefins with each other or with other vinyl monomers, preferably aliphatic vinyl monomers. The alloy according to claim 1, characterized in that the PO is a polyethylene. The alloy according to claim 1, characterized in that the PO is polypropylene. 6. The alloy according to claim 1, characterized in that the ratio of the surface tension of TPU and the surface tension of PO measured at a temperature above the melting point of the alloy is from 0.8 to 1.2.7. The alloy according to claim 1, characterized in that the Mn for poly-THF> 1000 g / mol. The alloy according to claim 1, characterized in that at least one functional group that can provide long-range interaction with one or more TPU segments is a group that can form hydrogen bonds with one or more TPU segments. The alloy according to claim 1, characterized in that the viscosity of the discrete phase relative to the viscosity of the matrix phase is from 10 to 0.1.10. Alloy p
