The invention relates to a process for preparing blends of high-performance polymers. The particular features are that at least two single-type polymers are treated with a solvent or a solvent mixture in which the polymers used are soluble, the polymers are thereby dissolved, and are then precipitated in a liquid medium, and recycled material is used for each of the polymeric constituents.

Polyarylene sulfide molding composition

A polyacetal molding composition comprising, as the active additive, at least one a) ester of long-chain monocarboxylic acids (C.sub.22 to C.sub.34) with mono- or polyhydric alcohols (C.sub.2 to C.sub.8), in the presence or absence of alkali metal and/or alkaline earth metal salts of the carboxylic acids mentioned, and/or b) polyethylene wax, is distinguished by a reduced tendency toward melt fracture. Such molding compositions can advantageously be employed in the production of shaped articles which show no undesirable defects in the surface.

Polyacetal molding compositions and their use

A thermoplastic molding composition comprising (A) from 20 to 70% by weight of polyphenylene sulfide, (B) from 5 to 20% by weight of ultrahigh-molecular-weight polyethylene, (C) from 10 to 40% by weight of a fibrous reinforcing agent, (D) from 10 to 40% by weight of an inorganic filler, and (E) from 0 to 1% by weight of a lubricant and/or other additives is used to produce moldings, fibers and films having particularly good wear properties.
