PCT No. PCT/JP91/00471 Sec. 371 Date Jan. 22, 1992 Sec. 102(e) Date Jan. 22, 1992 PCT Filed Apr. 10, 1991 PCT Pub. No. WO91/15521 PCT Pub. Date Oct. 17, 1991.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.
