Abstract: A process for the preparation of filler-containing thermoplastic moulding compositions by mixing fillers with thermoplastics in the melt, where a) the fillers are mixed in a mixing device in the melt with a low-molecular-weight thermoplastic having a maximum melt viscosity of 30 Pas (measured at a temperature of 20 DEG C above the melting point of the thermoplastic and at a shear gradient of 1 000 s ), b) the resultant product is discharged from the mixing device, cooled and comminuted, and c) the comminuted product in the solid phase is subsequently subjected to post-condensation.

Abstract: Low-wear thermoplastic moulding materials (I) are claimed, contg. (A) 39-99.99 wt.% thermoplastic polymer, (B) 0.01-5 wt.% of a fullerene and (C) 0-60 wt.% normal additives. (I) pref. contain 99-99.9 wt.% (A) and 0.1-1 wt.% (B). (A) pref. consists of polyamide, PPE, polystyrene, polyethylene, polypropylene, polyester, polycarbonate, polyoxymethylene, ABS, SAN, ASA or a mixt. thereof. (B) is an opt. fluorinated 60C and/or 70C carbon modification (fullerene). (B) is prepd., e.g. by high-temp. vaporisation of graphite (d.c. heating) in a noble gas atmos. to give "carbon soot", followed by chromatography, fractional sublimation or extn. to give a mixt. contg. 10-30% 60C and 10% 70C fullerenes. (C) are, e.g. impact modifiers, stabilisers, PE wax, pigments, fire retardants etc.. USE/ADVANTAGE - For prodn. of moulded prods.. Also claimed are moulded prods. obtd. from (I). The incorporation of fullerenes gives moulding materials with improved abrasion resistance, suitable esp. for the prodn. of machine components, e.g. ball-bearing cage
