Copolymers of tert-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. tert-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.   5.      Safety A Material Safety Data Sheet has been compiled for tert-butyl acrylate that contains up-to-date information on all questions relevant to safety.   6.      Storage and handling In order to prevent polymerization, tertiary butyl acrylate must always be stored under air, and never under inert gases. The presence of oxygen is required for the stabilizer to function effectively. It has to contain a stabilizer and the storage temperature must not exceed 35 ℃。Under these conditions, a storage stability of one year can be expected. In order to minimize the likelihood of over storage, the storage procedure should strictly follow the “first-in-first-out” principle. Storage tanks and pipes should be made of stainless steel or aluminum. Although tertiary butyl acrylate does not corrode carbon steel, there is a risk of contamination if corrosion does occur. Regulations for the storage of flammable liquids must be observed (explosion-proof electrical equipment, vented tanks with flame arresters etc.). Storage tanks, pumps and pipes must be earthed.   7.      Note The data contained in this publication are based on our current knowledge and experience.
