Abstract
Synthetic plastic materials for the manufacture of extrusion, injection and press forms are described, which are prepared from elastomers as well as mixed- and copolymers thereof with thermoplastic properties and liquification products from extractive coal hydrogenation which are residues with a softening point between 50.degree. and 150.degree. C. Polar, aromatic or cyclic groups in the elastomer component increase the compatibility of the coal liquification residue with the elastomer and improve the mechanical properties of the products.
