Abstract

A fiber-reinforced molding composition, comprising: PA1 a) 97 to 50% by weight, relative to the sum of (a) and (b), of a mixture of 30 to 100 parts by weight of a polyphenylene ether, 0 to 70 parts by weight of a styrene polymer, 0 to 10 parts by weight of a polyoctenylene and 0.1 to 2.5 parts by weight of an .alpha.,.beta.-unsaturated carboxylic acid derivative or a precursor thereof; PA1 b) 3 to 50% by weight of carbon fibers and/or glass fibers whose surfaces bear functional groups which are capable of entering into chemical coupling reactions with the .alpha.,.beta.-unsaturated carboxylic acid derivatives; and optionally PA1 c) dyes, pigments, plasticizers, flame retardant additives, processing auxiliaries, other customary additives or combinations thereof.
