Abstract (en)

[origin: WO2015032681A1] The invention relates to the field of chemistry and to the blends that can by way of example be used for rolls and roll coverings in the printing, textile, paper and graphic industry. The problem addressed by the present invention is provision of blends that have improved physical properties, and of a simple low-cost process with low energy consumption for producing same. The problem is solved via blends of thermoplastic polyurethanes and rubbers, consisting of rubber and from 5 to 80% by weight of thermoplastic polyurethanes, where the materials intermesh with one another in the regions of contact between rubber and polyurethanes. The problem is further solved via a process in which at least one rubber and from 5 to 80% by weight of polyurethane precursors are mixed and homogenized, where the precursors are prepolymers made of polyisocyanate(s) and of macroglycol(s) and at least one chain extender, and/or monomers of polyisocyanates, of macroglycols and of chain extenders.
