WebThe reaction between the Fenton reagents (i.e., Fe 2+ and H 2 O 2 ) generates highly reactive hydroxyl radicals, which can act as radical initiators for the polymerization of vinyl monomers. Since the Fenton reaction is fast, easy to set up, cheap, and biocompatible, this unique chemistry is widely employed in various polymer synthesis studies ... In polymer chemistry, free-radical polymerization (FRP) is a method of polymerization by which a polymer forms by the successive addition of free-radical building blocks (repeat units). Free radicals can be formed by a number of different mechanisms, usually involving separate initiator molecules. Following its … See more Initiation is the first step of the polymerization process. During initiation, an active center is created from which a polymer chain is generated. Not all monomers are susceptible to all types of initiators. Radical … See more Contrary to the other modes of termination, chain transfer results in the destruction of only one radical, but also the creation of another radical. Often, however, this newly … See more In typical chain growth polymerizations, the reaction rates for initiation, propagation and termination can be described as follows: See more During polymerization, a polymer spends most of its time in increasing its chain length, or propagating. After the radical initiator is formed, it attacks a monomer (Figure 11). In an … See more Chain termination is inevitable in radical polymerization due to the high reactivity of radicals. Termination can occur by several different … See more There are four industrial methods of radical polymerization: • Bulk polymerization: reaction mixture contains only initiator and monomer, no solvent.
