ABSTRACT:
The method comprises mixing polymeric materials containing a filler with a hydrocarbonaceous solvent in a ratio of from 1:0.5 to 1:60 parts by mass.
The above mixture is isothermally heated to provide for a thermal decomposition of the polymeric materials and for a thermal decomposition of the polymeric materials and for a formation of a suspension.
Low-boiling fractions are distilled from the formed suspension in the presence of an inert gaseous agent at a temperature of 50.degree. to 400.degree. C. and at a pressure of 1.multidot.10.sup.2 to 1.multidot.10.sup.5 n/m.sup.2.
