Structural formula:
Stable at room temperature and pressure, avoid contact with oxide heat and ultraviolet radiation free radical initiator.
This product has a certain toxicity. The oral LD50 of rats was 1.0g/kg. There is obvious irritation after inhalation. The degree of skin irritation is mild, but the eye damage is more serious. Operators should wear protective glasses.
Store under dry, inert gas, keep the container sealed, and store in a cool, dry place
Packed in galvanized iron drums. Store in a cool and ventilated place. The warehouse should be dedicated and not mixed with other items. Pay attention to fire prevention. Anti-polymerization agent should be added before storage and transportation.
As a reactive monomer 2-Hydroxyethyl acrylate is used as a crosslinking agent for resins, plastics and rubber modifiers. Further, it is used in the synthesis of amphilic block copolymers by nitroxide mediated living radical polymerization. In addition to this, it is used to prepare tuned poly(hydroxyethyl acrylate) by atom transfer radical polymerization and also use in UV inks, adhesives, lacquers, artificial nails, etc.
