Perchloric Acid, an Effective Catalyst for Thermosetting Self‐Crosslinking Hydroxy Acrylic Resins

Journal of Applied Polymer Science, Volume 143, Issue 4, January 20, 2026.
Perchloric acid is an effective catalyst for the crosslinking of hydroxy acrylate resins. Its action is based on the intermediate formation of alkyl perchloric esters. Transesterification gives volatile alkyl perchlorates that evaporate to give a catalyst‐free resin.
