Abstract
Abstract Thermoplastic molding materials contain, as essential components, (A) from 2 to 97.9% by weight of a nylon, (B) from 2 to 97.9% by weight of a polyaryl ether ketone and (C) from 0.1 to 30% by weight of a polymeric component containing hydroxyl groups and in addition (D) from 0 to 50% by weight of an impact-modifying rubber and (E) from 0 to 60% by weight of fibrous and/or particulate fillers.

Claim 1
Independent Claim
159 words
A thermoplastic molding material containing, as essential components, (A) from 2 to 97.9% by weight of a nylon, (B) from 2 to 97.9% by weight of a polyaryl ether ketone and (C) from 0.1 to 30% by weight of a polymeric component containing essentially free available hydroxyl groups with the proviso that components A and B are stable to component C, said polymeric component being selected from the group consisting of: (1) a polycondensate of aliphatic or aromatic diols with eiphalohydrins, (2) a polymer selected from the group consisting of polyolefins, polystyrene or rubber elastomers or mixtures thereof having hydroxyl groups, (3) a polymer or copolymer or mixtures thereof containing up to 100 mol% of vinylphenylcarbinols or vinylphenyldimethylcarbinols or mixtures thereof, and (4) a non-crosslinked and soluble phenol/formaldehyde polycondensate, and in addition (D) from 0 to 50% by weight of an impact-modifying rubber and (E) from 0 to 60% by weight of fibrous or particulate fillers or mixtures thereof.
