Abstract
A method of processing polymer materials, highly filled or otherwise to recover cyclic structures or monomers. The method involves providing a vessel having a heated side wall, an agitator, and at least one of an additional heated structure, other than the heated side wall, within the vessel and means for forming a thin coat of material processed in the vessel on said heated side wall. A polymer material is fed into the vessel and heated to a sufficient temperature to cause depolymerization of the polymer material into cyclic structures or monomers. The cyclic structures or monomers are removed from the vessel and collected. The method does not require the use of a solvent.
