ABSTRACT:
A process for the preparation of modified pitches and low boiling aromatics and olefins is described. Waste plastic which consists of polymeric chains of olefins is subjected to a thermal treatment in the presence of high boiling aromatics. The modified pitches may be used for the production of carbon articles of high value.
