Used primarily as a monomer in the synthesis of specialty polymers and resins. Its structure allows for copolymerization with other vinyl compounds, enhancing thermal stability and mechanical strength of the resulting materials. Commonly found in high-performance coatings, adhesives, and optical materials due to its ability to form rigid, transparent polymers. Also utilized in the development of photoresists for semiconductor manufacturing, where precise patterning and durability are required. Its carboxylic acid group enables chemical modification for improved solubility or crosslinking in polymer systems.
