ABSTRACT OF THE DISCLOSURE Compositions comprising a) between 0.1 to 5% sulfur present as at least one member of the class consisting of elemental sulfur, aliphatic and aromatic dithiols, polymeric oxidation products thereof comprising repeat units of the formula -R-S-S- where R is a bivalent aliphatic or aromatic radical and inorganic sulphides by weight and b) a poly(aryl ether ketone); useful because of their high tensile modulus, high-temperature adhesive properties, and dimensional stabi- lity. In a further embodiment the composition further con- tains a reinforcing filler such as glass or carbon fibers. In a further embodiment the composition may be made into fibers or used as adhesives.
