Catalytic Degradation of Unsaturated Polyester Resins Using p ‐Toluenesulfonic Acid and n ‐Butanol for High‐Value Chemical Recovery
Unsaturated polyester resin (UPR) is one of the three major thermosetting resins. It has a three‐dimensional structure that is insoluble and non‐meltable. Owing to its outstanding mechanical performance and corrosion resistance, it has been widely applied in the domain of composite materials. However, its waste is...
