Used as a monomer in polymer chemistry, particularly in the synthesis of functional polymers and copolymers. Its vinyl group enables free-radical polymerization, while the amide functionality provides polarity and hydrogen bonding capability, making it useful in designing materials for sensors, separation membranes, and responsive gels. It is also employed in surface modification and grafting applications due to its reactivity and ability to influence polymer hydrophilicity. Additionally, it serves as an intermediate in organic synthesis where a reactive aromatic amide with polymerizable vinyl functionality is required.
