Abstract
The method includes the steps of feeding a polymer to an extruder where the polymer is melted, metering the molten polymer from the extruder to a tubular pyrolysis reactor through metering means connected to the extruder, and pyrolytically decomposing the polymer in the tubular pyrolysis reactor in the presence of a higher fatty acid, and/or a hydrochloric acid acceptor.
