BOC Sciences is dedicated to offering comprehensive and advanced polymer synthesis services for multiple monomers. Our services are highly flexible in addressing your unique demands, and our experienced experts will work in close collaboration with your research team to effectively support the polymer development projects.
Free radical polymerization (FRP) is a crucial synthesis route for obtaining a wide variety of different polymers and materials composites. This particular polymerization offers high compatibility with a wide range of monomers and makes the polymerization of highly specific monomers possible. FRP involves long-chain free radicals as propagating species, usually initiated by the attack of free radicals derived by thermal or photochemical decomposition of initiators. Polymerization proceeds by the addition of free radical chains to the double bonds of monomer molecules. Finally, two propagating species (growing free radicals) combine or disproportionate to terminate the chain growth. Because of its versatility, synthetic ease, compatibility with various functional groups, as well as tolerance to water and protic media, free radical polymerization has been widely used in industry and academia to synthesize different polymeric materials.

The popularity of free-radical polymerization is in substantial part due to the various advantages that this synthetic route offers with industrial applications. The polymerization process is noteworthy for its ease, convenience, and relative insensitivity to impurities, such as water and oxygen, which plague ionic polymerizations. Another advantage of free-radical polymerization is that it offers a convenient approach to designing and synthesizing various specialty polymers in almost every area. However, as the lifetime of an individual chain is short compared to the processing time, variations in the operating conditions (temperature, viscosity, monomer concentration, and composition) lead to increased heterogeneity in polymer composition, MW, and branching. Currently, free radical polymerization has found applications in the manufacture of polystyrene, thermoplastic block copolymer elastomers, cardiovascular stents, chemical surfactants, and lubricants. Nevertheless, free radical polymerization has uses in research as well, such as in the functionalization of carbon nanotubes and the synthesis of nanocomposite hydrogels.
