Tertiary butyl acrylate (tBA) Acrylic acid ester 1663-39-4 BASF Specialty Monomers Acrylic Monomers >> Reactive / Multifunctional (MFM) Acrylic acid ester for manufacturing polymers and for use as a feedstock for syntheses. Tertiary butyl acrylate forms homopolymers and copolymers. Copolymers of tertiary butyl acrylate can be prepared with acrylic acid and its salts, amides and esters, and with methacrylates, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, unsaturated polyesters and drying oils, etc. Tertiary butyl acrylate is also a very useful feedstock for chemical syntheses, because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds.
