Method of recycling cured unsaturated polyester resin waste

摘要

A method which can recycle waste by chemically treating cured unsaturated polyester resin waste and obtaining industrially useful raw material is provided. The cured unsaturated polyester resin waste is decomposed with a decomposition component such as dicarboxylic acid or diamine, to obtain resin raw material. Unsaturated polyester resin is re-synthesized with this resin raw material, to chemically recycle the same.
