Beta-Carboxyethyl Acrylate, >98% Active

Beta-Carboxyethyl Acrylate, high purity material is in the class of carboxylic monomers of the acrylic or methacrylic acid type. A significant difference is the greater separation of the carboxylic acid functionality from the polymerizable vinyl functionality.

Can be polymerized in solution or emulsion to produce acrylic, vinyl-acrylic or styrenic-acrylic polymers with improved adhesive properties.

Other 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.
