Product Description
Diacetone Acrylamide (DAAM), CAS No. 2873-97-4, is a functional organic monomer used in polymer synthesis and resin formulation. With the molecular formula C9H15NO2 and molecular weight of 169.22 g/mol, this compound contains a polymerizable acrylamide group and a reactive ketone group, making it valuable for developing functional copolymers and crosslinkable polymer systems.
As a Diacetone Acrylamide monomer, DAAM can be incorporated into suitable polymer structures through copolymerization with compatible monomers. The ketone functionality can subsequently participate in crosslinking reactions with appropriate crosslinking agents, including adipic acid dihydrazide (ADH), under suitable formulation conditions.
Diacetone Acrylamide for waterborne coatings and adhesives is particularly relevant to the development of functional acrylic emulsions and other water-based polymer systems. Depending on the formulation and curing conditions, DAAM-based crosslinking systems can help improve properties such as adhesion, water resistance, stain resistance, and film durability.
Diacetone Acrylamide is also used in selected applications involving textile treatment, paper treatment, photosensitive resins, and resin modification. Its suitability depends on monomer purity, residual acrylamide content, stabilizer composition, polymerization conditions, and the requirements of the finished product.
For industrial buyers seeking DAAM CAS 2873-97-4, important procurement factors include assay, appearance, melting point, moisture content, residual acrylamide, inhibitor or stabilizer details, packaging, and batch-specific quality documentation.
