Itaconic acid is an unsaturated dibasic organic acid that contains unsaturated double bonds and has active chemical properties. It can undergo various addition reactions, esterification reactions, and polymerization reactions. For these reasons, itaconic acid is an important raw material for the chemical synthesis industry and chemical production. Itaconic acid and its polymers can be used to make high-efficiency deodorants, papers with deodorizing functions, plastic films, and other products. It can also be polymerized with styrene and butadiene to make SBR latex for uses like paper coating and carpet sizing. Additionally, itaconic acid is used to produce derivatives that can function as pharmaceuticals, cosmet
