Claim 1

Mixtures consisting of A) 99.5 to 93% by weight of unbranched polyarylene sulphide free from sulphone groups, B) 0.5 to 7% by weight of a maleimide of the formula (I) or (II), or a mixture of (I) and (II) ##STR2## wherein R 1 and R 2 can be identical or different and each denotes hydrogen, C 1 -C 22 -alkyl, C 6 -C 14 -aryl, or C 7 -C 22 -aralkyl or C 7 -C 22 -alkylaryl, R 3 , R 4 and R 5 independently of one another are divalent radicals with 1 to 38 cyclic or acyclic aliphatic carbon atoms, divalent aromatic radicals with 6 to 24 carbon atoms, divalent aromatic-aliphatic or aliphatic-aromatic radicals with 7 to 40 carbon atoms, or at least two of R 3 , R 4 and R 5 being aromatic or aliphatic rings linked by a chemical bond, C 1 -C 10 -alkylene group, an oxygen atom, a sulphur atom, a disulfide group, a carbonyl group or a sulphone group, X represents --NH or C 1 -C 10 -N-alkyl, and m represents a number from 0 to 1,000, and C) based on 100 parts by weight of the sum of (A+B), 10-400 parts by weight of glass fibers which are sized with polyurethane film-forming agents and aminosilane adhesion promoters or other mineral fillers, reinforcing substances or inorganic or organic auxiliaries, wherein at least 30% by weight of the fillers and reinforcing substances are glass fibers.
