“…Therefore, the design of a synthetic route is crucial to produce macromolecules with the desired architecture and functionalities. Since the 2000s, the numerous publications and reviews summarized the application of click reactions in the synthesis of macromolecules with complex architecture [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. Nowadays, click reactions are used to assemble macromolecules, the parts of which are pre-prepared by living anionic polymerization, pseudo-living cationic polymerization, and reversible deactivation radical polymerization (RDRP) [ 39 ].…”

The parallel development of reversible deactivation radical polymerization and click reaction concepts significantly enriches the toolbox of synthetic polymer chemistry. The synergistic effect of combining these approaches manifests itself in a growth of interest to the design of well-defined functional polymers and their controlled conjugation with biomolecules, drugs, and inorganic surfaces. In this review, we discuss the results obtained with reversible addition–fragmentation chain transfer (RAFT) polymerization and different types of click reactions on low- and high-molar-mass reactants. Our classification of literature sources is based on the typical structure of macromolecules produced by the RAFT technique. The review addresses click reactions, immediate or preceded by a modification of another type, on the leaving and stabilizing groups inherited by a growing macromolecule from the chain transfer agent, as well as on the side groups coming from monomers entering the polymerization process. Architecture and self-assembling properties of the resulting polymers are briefly discussed with regard to their potential functional applications, which include drug delivery, protein recognition, anti-fouling and anti-corrosion coatings, the compatibilization of polymer blends, the modification of fillers to increase their dispersibility in polymer matrices, etc.

“…3 For these reasons, these polymers are widely used in the automobile industry and materials science, including as separators in lithium ion batteries, UV-resistant coating materials, and organic bulk heterojunction. 3 However, fluorinated homopolymers suffer from a few drawbacks, including (i) high crystallinity (which leads to expensive processing), (ii) poor solubility in common organic solvents (resulting in characterization limitations), and (iii) difficulty in cross-linking/functionalization. The incorporation of functional comonomer(s) into the backbone of the fluorinated homopolymers might resolve these issues.…”

Well-defined fluoropolymers exhibit unique properties such as excellent oil and water repellency, satisfactory thermal stability, low refractive index, and low surface energy.The origin of these properties is attributed to the presence of strong electronegative and low polarizable Fluorine atom in the backbone of such polymers which leads to a strong C F bond (with a high bond dissociation energy of 485 kJ mol −1 ). Due to these features, these polymers have found applications as functional coatings, thermoplastics, biomedical items, separators and binders for Li-ion batteries, fuel cell membranes, piezoelectric devices, high quality wires and cables, etc. Usually, fluoropolymers are synthesized by conventional radical (co)polymerization of fluoroalkenes which leads to the production of (co)polymers with ill-defined end group, uncontrolled molar mass, and high dispersity values. In the last two decades, significant developments of various reversible deactivation radical polymerization (RDRP) techniques have helped the design of macromolecular architectures (including block, graft, star, dendrimers) on demand. However, for relevant new applications, well-defined fluoropolymers with well-defined macromolecular architectures (e.g. block copolymers as thermoplastic elastomers and electroactive polymers or graft copolymers for fuel cell membranes) are required.Several RDRP methods developed in the last couple of decades have paved the way for the synthesis of (co)polymers with well-defined molar mass, dispersity, chain end-functionality and
