摘要

A decomposition reaction apparatus for the decomposition treatment of athermoplastic resin, which comprises a reaction apparatus comprising anintroduction section for introducing a resin composition containing thethermoplastic resin and a solvent containing a monomer component of thethermoplastic resin or a component similar to the monomer component, adecomposition reaction section for heating and pressuring the resincomposition and the above solvent so as for the solvent to have asupercritical state or a subcritical state, to thereby prepare a treated andrecovered product containing a recycled resin formed by the reduction of themolecular weight of the above thermoplastic resin, and a discharge section fordischarging the treated and recovered product. In the above reactionapparatus, the introduction of the resin composition and the solvent, thedecomposition treatment of the thermoplastic resin in the decompositionreaction section and the discharge of the treated and recovered product fromthe discharge section are all carried out continuously, and therefore, a rawmaterial for a recycled resin composition using an industrial or general wastecontaining a thermoplastic resin as the above resin composition can beproduced continuously.
