General description
1,2,4-Benzenetricarboxylic anhydride(TA) is a hydrophilic monomer with multipurpose usage; as a curing agent for epoxy based resins and as a plasticizer for polyvinyl chloride(PVC).
Application
TA can chemically modify sugarcane bagasse, which can be used in the absorption of auramine and safranin dyes from aqueous solutions. It can be blended with epoxy propane in the synthesis of polyurethane acrylates, which can be used as oligomers for ultra-violet based coatings. Polyamide P84 ultra-filtration membranes can be functionalized with TA by interacting the amide linkages with the anhydrides.
