Product Application of Diacetoneacrylamide (CAS#2873-97-4)
Diacetoneacrylamide is an important functional vinyl monomer widely used in advanced polymer synthesis and material modification. Its homopolymer is insoluble in water but exhibits unique moisture-regulating (“water-breathing”) properties. It can absorb approximately 20–25% of its own resin weight in water and gradually release the absorbed moisture when environmental humidity decreases, with water acting as a plasticizing component to improve polymer flexibility and performance.
1. Moisture-Resistant Hair Styling Resins
Diacetoneacrylamide is used in the formulation of high-performance hair perm and styling resins, particularly in Japan. Materials containing this component provide excellent shape retention and humidity resistance, helping hairstyles maintain their form even under exposure to moisture, rain, or washing conditions.
2. Photosensitive Resin Applications
As a functional component in photosensitive resin systems, Diacetoneacrylamide contributes to:
Fast photo-curing response
Clear pattern formation after exposure
Easy removal of unexposed areas
Improved mechanical strength, solvent resistance, and water resistance of cured materials
It is also used as a functional additive in various resin systems, including:
Crosslinking agent for unsaturated polyester resins
Crosslinking agent for diallyl phthalate resins
Curing agent component for epoxy resin systems
3. Specialty Polymer and Industrial Applications
Due to its reactive ketone groups and excellent moisture-control characteristics, Diacetoneacrylamide is widely applied in the development of functional materials, including:
Moisture-permeable (“water-breathing”) polymers such as contact lens materials, anti-fog coatings, and marine protective coatings
Pressure-sensitive adhesives and adhesive modifiers
Nonwoven fabric binders
Water-absorbing films
Leather finishing agents and surface modifiers
Paper strengthening additives
Antistatic polymers
Specialty inks
With its unique combination of polymerization activity, crosslinking ability, and moisture-responsive properties, Diacetoneacrylamide serves as a valuable functional monomer for coatings, adhesives, resins, and high-performance polymer materials.
