Beta-Carboxyethyl Acrylate, Distribution

Synonyms: BETA-C, 2-Carboxyethyl acrylate

Key differences compared to conventional carboxylic acid functional materials are:

• Promotes flexibility in polymers owing to lower glass transition of its homopolymers (< 30°C).
• Provides improved adhesion and stability in emulsion polymers, due to its -COOH groups being more available than those in the conventional carboxylic acids.
• Much more reactive in its salt form than acrylic acid, allowing high levels of incorporation, over a wide pH range.
• More compatible with other monomers, thus reducing aqueous phase polymerization and producing more uniform copolymers.
