APPARATUS FOR THERMAL DECOMPOSITION OF POLYMERIC MATERIALS ABSTRACT An apparatus comprises a reaction chamber provided with a charging hole, a branch pipe for discharging a suspension, and with a branch pipe for withdrawing a va- pour-gas phase, the latter being communicated with a condenser. The apparatus comprises a heater provided with a heat-exchanger for preheating a solvent, said he- at-exchanger being introduced into said heater and com- municated with the reaction chamber through nozzles ada- pted for a jet feeding of the solvent into the reaction mass. At the outlet of the reaction chamber there is in- stalled a distillation column communicated with the branch pipe for discharging the suspension and provided in the upper portion thereof with a branch pipe for with- drawing the vapour-gas phase, while in the lower portion thereof there is provided a branch pipe for discharging a distillation residue. Such an apparatus allows the range of the end pro- ducts to be expanded and the quality thereof to be up- graded, providing simultaneously for the continuity of the process of refining the polymeric materials.
