Description

General description

Acrylic acid (AAc) is a colorless, unsaturated carboxylic acid. It is miscible in water and alcohol. It often finds application as an chemical intermediate.

Application

AAc is used in preparing monodispersed poly (N-isopropylacryamide) (PNIPAM)/AAc microgels. AAc has been plasma-deposited on surfaces for cell culture applications. Surface modification of poly(ethylene terephthalate) (PET) films via UV-induced graft copolymerization with AAc has been reported. AAc is used primarily as an intermediate in the production of acrylates.
