摘要：
The present invention relates to a plastics mixture comprising at least one thermoplastic polyurethane A) and at least one impact-modified poly(meth)acrylate B), where the impact-modified poly(meth)acrylate comprises a hard phase whose glass transition temperature is at least 70° C. and a tough phase whose glass transition temperature is at most −10° C., the average particle size of the tough phase is at most 130 nm, and at least a portion of the tough phase has covalent linkage to the hard phase.
