Product Name:β-Acryloyloxypropionic acid
English Name:β-Acryloyloxypropionic acid
CAS No.:24615-84-7
Aliases:β-Carboxyethyl acrylate, β-CEA, 2-Carboxyethyl acrylate
Molecular Formula:C6H8O4
Physical Properties:Colorless to slightly yellowish transparent low-viscosity liquid, molecular weight 144.12. Density (25°C) 1.17–1.20 g/cm³, viscosity (25°C) 60–80 mPa·s, flash point 87°C. Decomposes at high temperature without atmospheric boiling point; distillable under high vacuum. Miscible with water, alcohols, ketones, esters, and aromatic hydrocarbons. Homopolymer Tg is 37°C with flexible side chains and low steric hindrance. Acid value approx. 385–395 mgKOH/g, strongly acidic. Prone to decarboxylation and self-polymerization above 130°C; requires inhibitor for storage.
Uses:Used as a bifunctional acrylic functional monomer for synthesizing waterborne emulsions, UV-curable resins, and coatings. Its carboxyl group undergoes crosslinking with epoxy, aziridine, and isocyanate groups, significantly enhancing adhesion of films to metals, glass, and plastic substrates. It also improves emulsion stability, pigment dispersion, and coating flexibility while reducing polymerization shrinkage, making it suitable for high-performance adhesives, inks, and surface treatment agents.
