Used as a key intermediate in the synthesis of polymers, particularly in the preparation of functionalized polyolefins and block copolymers. It plays a crucial role in atom transfer radical polymerization (ATRP), a technique widely employed to create well-defined polymers with controlled molecular weights and architectures. The compound is also utilized in surface modification processes, enabling the grafting of polymer brushes onto various substrates for applications in biomaterials, coatings, and nanotechnology. Its reactive double bond and bromine functionality make it valuable for designing advanced materials with tailored properties.
