2,2‑Bis(hydroxymethyl)propionic Acid (DMPA) is a multifunctional monomer featuring both carboxylic acid and hydroxyl groups, making it highly valuable for high‑performance polymer systems. It is widely used in the formulation of anionic polyurethane dispersions, waterborne coatings, and emulsifiable polyurethanes, where its hydrophilic functionality improves dispersibility and film formation. In addition, DMPA serves as an AB₂ monomer in the synthesis of hyperbranched polymers and dendrimers, enabling materials with enhanced branching, multifunctionality and tailored architectures for advanced applications in adhesives, coatings, and specialty polymers.
