“…[273] The visible light-induced ITP using bifunctional alkyl and perfluoroalkyl iodides afforded telechelic poly(vinylidene fluoride)s with very high (> 95 %) iodide chain-end fidelity, which were further utilized for preparation of a series of ABA triblock copolymers containing vinyl acetate, tert-butyl acrylate, methyl methacrylate, isoprene, styrene, and acrylonitrile segments. [274][275][276] The influence of UV light on photomediated ITP was also investigated under various experimental conditions. [277] ITPs of butyl methacrylate with cyanopropyl iodide as chain transfer agent and a conventional initiator, AIBN, were conducted at 60 °C under dark conditions and in the presence of UV light.…”

Photomediated controlled radical polymerization is a versatile method to prepare, under mild conditions, various well-defined polymers with complex architecture, such block and graft copolymers, sequence-controlled polymers, or hybrid materials via surface-initiated polymerization. It also provides opportunity to manipulate the reaction through spatiotemporal control. This review presents a comprehensive account of the fundamentals and applications of various Photomediated CRP techniques, including atom transfer radical polymerization (ATRP), reversible addition-fragmentation chain transfer (RAFT), nitroxide mediated polymerization (NMP) and other procedures. In addition, mechanistic aspects of other photomediated methods are discussed.

“…As expected, M n remained independent of conversion (M n ∼ 4−5000) with rather narrow PDI values of ∼1.3−1.5, partially attributable to MeOH precipitation of oligomers. 1,[39][40][41][42][43][44][45][46]53 Interestingly, both M n and the reaction rates…”

Group 14 (Mt = Sn, Ge, Pb) R3MtX, R4Mt, and R6Mt2 complexes (R = alkyl, aryl; X = H, halide, etc.) are introduced as novel, universal, visible and black light bulb (BLB)/UV photoinitiators for free radical photopolymerization of alkenes, including vinylidene fluoride (VDF), vinyl acetate, methyl methacrylate, styrene, and butadiene. A comprehensive solvent, ligand and metal comparison for VDF indicates progressively faster BLB photopolymerizations in acetonitrile (ACN) ∼ dimethylacetamide (DMAc) < dimethyl sulfoxide (DMSO) < butanone < propylene carbonate < acetic anhydride ∼ cyclohexanone < dimethyl carbonate and especially in the photosensitizing acetone, where Me2SnI2 ∼ Ph3SnI ∼ Bu3Sn–N3 ∼ Bu3Sn–CH2–CHCH2 ≪ Bu3Sn–S–SnBu3 < Ph4Ge < Ph6Pb2 < Bu3Sn–I < Bu4Sn < Ph6Sn2 < Bu3Sn–Br < Ph6Ge2 < Oct4Sn < Bu4Ge < Bu3Sn–Cl < Ph4Pb < Bu3Sn–H ≪ Bu6Sn2 ≪ Me6Sn2 and where M n is controlled by solvent chain transfer. Photoinitiation results from a combination of R3Mt·, R·, and solvent (S·, e.g., CH3–CO–CH2·) radicals, where R6Sn2 (R = Me, Ph) initiates as R3Sn·, all Bu derivatives, as both Bu3Sn· and Bu·, and Ph4Mt and Ph6Mt2 (Ge, Pb), only indirectly via S·. Interestingly, while R3Sn–CH2–CF2-poly(vinylidene fluoride) (PVDF) eliminates R3SnF to afford CH2CF–PVDF macromonomers, nonfluorinated alkenes are initiated even in bulk under visible light and do not undergo R3SnH elimination.

“…The melting points of the hard blocks containing either poly(ethylene-alt-CTFE) or poly(ethylene-alt-TFE) copolymers were 247 or 252 °C, respectively (Scheme 6.3). [46] They later employed this Mn 2 (CO) 10 -system to prepare well-defined sulfonated and fluorinated block copolymers for potential application in fuel cell membranes 222 Functional Polymers by Reversible Deactivation Radical Polymerisation: Synthesis and Applications by sequential copolymerisation of neopentyl styrene sulfonate and VDF [47]. Subsequently, they employed hypervalent iodide carboxylate, (CX 3 CO 2 ) 2 I III Ph, to develop a metal-free protocol in conjunction with external [I(CF 2 ) 6 I] and in situ generated (CF 3 I) iodinated CTA to achieve the RDRP of VDF and to produce poly(VDF)-b-poly(M) block copolymers [48] [where 'M' stands for styrene (S), butadiene, 2,2,2-trifluoroethyl methacrylate (TFEMA), and surprisingly methyl-2-(trifluoromethyl) acrylate], known not to homopolymerise under radical conditions [49].…”
