Free Radical Polymerization FRP

the concentration of initiator, radical-liable moieties, and nature of solvent system all have a collective influence over the rate, stability, and kinetics of network formation. These parameters, in turn, reflect on the overall performance of the material in terms of cross-linking density, mechanical properties, and degradation profiles. Distinct differences in the application of systems cross-linked through photo-initiated and redox-initiated mechanisms have been reported in various literatures. For

Scheme 7.36 Synthetic scheme for the polymerization of norbornene and its derivatives via free radical polymerization (FRP), ring-opening metathesis polymerization (ROMP), and vinyl addition polymerization (VAP) techniques. Polymers I, II, and III are isomers that differ in their enchainment and physical properties. Co- and terpolymerization of norbornene and derivatives of norbornene with other alicyclic monomers such as maleic anhydride, methyltetracyclododecene carboxylic acid, etc. are also successfully synthesized with this scheme. (Note that 2, 3- and 2,7-enchainments of repeating units are reported in type I polymers. °°)...

Singha et al. reported DA cross-linked products [158] using furan-modified polymethacrylate (PFMA) as the polymeric precursor, which was prepared through atom transfer radical polymerization (ATRP) and free-radical polymerization (FRP). Furthermore, the self-healing behavior of a triblock copolymer (PFMA-co-MMA) prepared by ATRP was demonstrated by means of scanning electron microscopy (SEM). With the modification, an almost fully recovered surface from knife-cut samples has been observed [159]. Chen et al. also reported the DA polymer product of PFMA-BM possessing thermal reversibility, whereas the homopolymer was prepared from anionic polymerization [160]. 

Free radical polymerization (FRP) is a very widespread method of polymerization, which has been used for a long time in industiy for many reasons FRP is easy to carry out, can be performed in bulk, in solution in various solvents, and also in dispersed media (suspension, emulsion, etc.). It can be achieved over a large range of reaction temperatures (—100 to -1-200 °C). Additionally, this polymerization technique can be carried out with a lot of monomers, even functionalized ones. For example, monomers can bear standard functional groups or heteroatoms such as silicon or phosphorus. 

Living radical polymerization (LRP) is developed on the basis of conventional free-radical polymerization (FRP). The main idea behind this development is to overcome intrinsic shortcomings of FRP without sacrificing any of its strengths. These strengths are... 

Most of the MIPs are fashioned through the free-radical polymerization (FRP) procedures that are initiated upon the decomposition of a radical producing compound, referred to as the initiator, by means of thermal or photochemical stimuli. Such reactions are commonly conducted imder mild temperature and pressure conditions. The FRP is appropriate for a variety of functional monomers and templates [28]. According to the general pattern of free-radical reactions, after the initiation phase, the number of the free radicals increases, leading to the propagation stage where the main portion of...
