    Uses
    Used as organic synthesis intermediates, binders, emulsifiers, coatings. Oleic acids and their esters are widely used in industry. Acrylates are often polymerized into polymers or copolymers during use. N-butyl acrylate (and methyl ester, ethyl ester, 2-ethylhexyl ester) is a soft monomer that can be combined with various hard monomers such as methyl methacrylate, styrene, acrylonitrile, vinyl acetate, etc. The monomer is copolymerized, crosslinked, grafted, etc., such as hydroxyethyl (meth) acrylate, hydroxypropyl acrylate, glycidyl ester, (meth) acrylamide, and a base derivative, to prepare 200-700 kinds of acrylics. Resin products (mainly emulsion, solvent and water soluble), widely used in coatings, adhesives, acrylic fiber modification, plastic modification, fiber and fabric processing, paper treatment, leather processing and acrylic rubber .
