The purpose of this review is to critically assess the kinetic behavior of the furan/maleimide Diels-Alder click reaction. The popularity of this reaction is evident and still continues to grow, which is likely attributed to its reversibility at temperatures above 100 °C, and due to its biobased "roots" in terms of raw materials. This chemistry is used to form thermoreversible crosslinks in polymer networks, and thus allows the polymer field to design strong, but also end-of-life recyclable thermosets and rubbers. In this context, the rate at which the forward reaction (Diels-Alder for crosslinking) and its reverse (retro Diels-Alder for decrosslinking) proceed as a function of temperature is of crucial importance in assessing the feasibility of the design in real-life products. Differences in kinetics based from various studies are not well understood, but are potentially caused by chemical side groups, mass transfer limitations, and the analysis methods being employed. In this work, all the relevant studies are attempted to be placed in perspective with respect to each other, and thereby offer a general guide is offered on how to assess their recycling kinetics.

“…Hence, they can lead to thermoreversible crosslinked materials, which can be used as thermoresponsive materials. Accordingly, RDRP copolymers containing FMA repeat units have been widely investigated for applications such as selfhealing materials, [129][130][131][132] responsive nanoparticles, [133] smart hydrogels, [134] and surfaces. [135] Representative examples are selfhealable materials based on well-defined ABA triblock copolymers containing reactive PFMA end blocks.…”

Currently, most commodity chemicals and polymers are manufactured from nonrenewable petroleum-based resources. However, due to its finite nature and social claims about environment preservation, alternative sources of value-added and building block chemicals are being intensively studied. Renewable lignocellulosic biomass has offered an attractive replacement for fossil-based chemicals. Lignin and C5/C6 sugars obtained from lignocellulosic biomass through chemical and enzymatic methods can be further transformed to targeted chemical platforms. In the present review, synthetic pathways for well-defined poly(meth)acrylates obtained from C5/C6 sugar-derived platforms in which the sugar structure is not retained are discussed. While bio-based polymers from these monomers are investigated using a wide range of polymerization techniques, this study focuses on precise synthesis of macromolecular structures taking advantage of reversible-deactivation radical polymerization methods and their applications.

“…ATRP is one of the most important living/controlled free radical polymerizations. Compared with the traditional free radical polymerization, ATRP has the characteristics of a controllable molecular weight of the polymer and a narrow molecular weight distribution, and ATRP is usually used in polymer molecular design to customize the molecular structure and function of polymers. − Cao et al successfully copolymerized various vinyl monomers, including acrylate, styrene, acrylonitrile, and acrylamide, with α-haloacrylate by the ATRP technology, which realized chain growth, and a high monomer conversion rate and produced well-defined branched polymers with tunable degrees of branching . Tamura et al first synthesized the macromonomer poly(methyl methacrylate) (PMMA) by the ATRP technology and then prepared a PMMA bottle brush polymer by ring-opening metathesis polymerization then used the PMMA bottle brush polymer to effectively control and eliminate the orientation birefringence of the optical polymer PMMA .…”

Polystyrene (PS) is widely used in our daily life, but it is flammable and produces a large number of toxic gases and hightemperature flue gases in the combustion process, which limit its application. Improving the flame retardancy of PS has become an urgent problem to be solved. In addition, in view of the disadvantage that small-molecule flame retardants can easily migrate from polymers during use, which leads to the gradual reduction of the flame retardant effect or even loss of flame retardant performance, and the outstanding advantages of ATRP technology in polymer structure design and function customization, we used ATRP technology to synthesize the high-molecular-weight bifunctional additive PFAA-DOPO-b-PDEAEMA, which has flame retardant properties and antistatic properties. The chemical structure and molecular weight of PFAA-DOPO-b-PDEAEMA were characterized by FTIR, 1 H NMR, GPC, and XPS. When the addition of PFAA-DOPO-b-PDEAEMA was 15 wt %, the limiting oxygen index (LOI) of polystyrene composites was 28.4%, which was 53.51% higher than that of pure polystyrene, the peak of the heat release rate (pHRR) was 37.61% lower than that of pure polystyrene, UL-94 reached V-0 grade, and the flame retardant index (FRI) was 2.98. In addition, when the PFAA-DOPO-b-PDEEMA content is 15 wt %, the surface resistivity and volume resistivity of polystyrene composites are 2 orders of magnitude lower than those of polystyrene. This research work provides a reference for the design of bifunctional and even multifunctional polymers.
