Core Chemical Characteristics

Containing active carbon-carbon double bond and ester group, easy to undergo free radical polymerization, copolymerization with methyl acrylate, butyl acrylate, styrene, vinyl acetate, etc.
Self-polymerization risk: Polymerize rapidly under heating, ultraviolet light, peroxide initiator or without inhibitor, producing solid polyethyl acrylate; long-term high-temperature storage must be avoided.
Typical acrylate reaction: Addition reaction (Michael addition), graft copolymerization, crosslinking reaction for adhesive and coating film formation.
Hydrolysis: Slow hydrolysis in neutral water, accelerated under strong acid/alkali heating to generate acrylic acid and ethanol.
Incompatible substances: Strong oxidants, strong reducing agents, concentrated strong acids, strong alkalis, peroxide initiators, metal powder, polymerization accelerators.
