N-tert-Butylacrylamide丨CAS 107-58-4

N-tert-Butylacrylamide (CAS 107-58-4) is a versatile monomer widely used in the synthesis of specialty polymers and functional materials. It is primarily employed in the production of temperature- and pH-responsive polymers, such as poly(N-tert-butylacrylamide) and copolymers with acrylamide or other monomers, which are used in biomedical applications, drug delivery systems, and smart hydrogels. Its hydrophobic tert-butyl group provides tunable solubility and lower critical solution temperature (LCST) behavior, making it suitable for stimuli-responsive materials that swell or collapse in response to environmental changes. Additionally, it is used in coatings, adhesives, and surface modification, where it enhances hydrophobicity, chemical resistance, and thermal stability. N-tert-butylacrylamide is also applied in research and industrial polymerization studies to create functional copolymers and responsive networks for a variety of material science applications.

The benefits of N-tert-butylacrylamide come from its chemical versatility, hydrophobic modification, and stability under polymerization conditions. The tert-butyl group provides steric hindrance that improves polymer thermal and mechanical stability while allowing tunable hydrophilicity in copolymers. Its reactivity in free radical and controlled/living polymerization techniques enables precise control over polymer composition, molecular weight, and architecture. The monomer's solubility in organic solvents and compatibility with other acrylamide-based monomers facilitates easy incorporation into copolymers, hydrogels, and functional materials. These characteristics allow the creation of polymers with predictable stimuli-responsive behavior, enhanced durability, and targeted performance for biomedical, industrial, and materials science applications.
