Title:
METHOD FOR DECOMPOSING THERMOSETTING RESIN
Document Type and Number:
WIPO Patent Application WO/2005/103131
Kind Code:
A1
Abstract:
Disclosed is a method for decomposing a thermosetting resin which enables to collect monomers and/or oligomers at high yield, with high energy efficiency and high productivity. Specifically disclosed is a method for decomposing a thermosetting resin comprising a step for decomposing a thermosetting resin, which is obtained by crosslinking copolymers composed of a polyhydric alcohol and an acid using a crosslinking agent, into monomers and/or oligomers by using a supercritical or subcritical fluid in a reaction vessel; a step for producing a gas containing the monomers and/or oligomers by maintaining the reaction liquid in the reaction vessel at a temperature at which the monomers and/or oligomers evaporate; and a step for collecting the monomers and/or oligomers by collecting the gas.
