4-Hydroxybutyl Acrylate (4-HBA) forms homopolymers and copolymers. Copolymers of 4-Hydroxybutyl Acrylate (4-HBA) 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. 4-Hydroxybutyl Acrylate (4-HBA) is also a very useful feedstock for chemical syntheses, because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds.
