What is tert-Butylacrylamide?
tert-Butylacrylamide (CAS 107-58-4), commonly abbreviated as TBA, is a hydrophobic acrylamide monomer used to modify the functional properties of polymers.
Where is tert-Butylacrylamide used?
- Copolymer systems: tuning hydrophobicity, surface adhesion and rheological behaviour
- Personal care: copolymerized with acrylic acid into film-forming polymers and rheology modifiers for hair fixatives, styling gels and skin-care formulations
- Water treatment: TBA-based copolymers enhance flocculant performance and sludge dewatering in industrial effluent systems
- Coatings and adhesives: water resistance and substrate adhesion in architectural and industrial coating resins
- Textile and paper processing: surface-sizing agents and finishing auxiliaries that improve wet strength and surface uniformity
Commercial specifications
- Technical grade, purity typically 97–99% for polymerization
- Inhibited grades for safe storage, transport and long-term warehousing
