2-Hydroxypropyl acrylate (HPA) Acrylic ester 25584-83-2 BASF Specialty Monomers Acrylic Monomers >> Reactive / Multifunctional (MFM) Acrylic ester for manufacturing polymers and for use as a feedstock for syntheses. Hydroxypropyl acrylate forms homopolymers and copolymers. Copoly-mers of 2-hydroxypropyl 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. 2-Hydroxypropyl 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.
