DETAILS

Sigma Aldrich - 407585

Packaging
250 mL in poly bottle

Sigma Aldrich - 552348

Packaging
50, 500 mL in glass bottle
Application
Can be polymerized in solution or emulsion to produce acrylic, vinyl-acrylic, or styrenic-acrylic polymers with greater flexibility due to lower glass transition of itshomopolymer (<30C) and improved adhesion.
Features and Benefits
More reactive in its salt form than acylic acid, allowing high levels of incorporation over awide pH range. Also see Poly(2-carboxyethyl) acrylate, 407585.
