Abstract

1. Claims for the Contracting States : BE CH DE FR GB IT LI NL SE Use of aromatic polyether ketones with repeated units of the formula see diagramm : EP0025538,P4,F4 in which Ar stands for aromatic residues, which may be the same or different, in particular for residues of benzene, naphthaline or diphenyl, and in which n represents an integer from 50 to 200, for the production of insulated winding wires from copper by extrusion, so that the total film thickness of the insulation meets with the requirements of the German Industrial Standard DIN 46 435 (April 1977). 1. Claim for the Contracting State : AT Method for the production of insulated winding wires from copper by extrusion so that the total film thickness of the insulation meets with the requirements of the German Industrial Standard DIN 46 435 (April 1977), characterized in that aromatic polyether ketones with repeated units of the formula see diagramm : EP0025538,P5,F1 in which Ar stands for aromatic residues, which may be the same or different, in particular for residues of benzene, naphthaline or diphenyl, and in which n represents an integer from 50 to 200 are used.
