“…The hydroxyl groups on HEA were then used to ring-open L-lactide before the RAFT end group was used to chain extend another arm. Combining different polymerization techniques, such as ROP, 346 ATRP [347][348][349][350] or SET, 351 with RAFT has facilitated the synthesis of different star polymers. 347,350 For example, Kizhakkedathu and coworkers 347 synthesized a multifunctional initiator obtained from hyperbranched polyglycerol, bearing an ATRP initiator and azo-initiator; the authors used the azo-initiator to initiate a RAFT polymerization whilst simultaneously performing an ATRP initiation.…”

Reversible addition fragmentation chain transfer (RAFT) polymerization is one of the most extensively studied controlled/living radical polymerization methods that has been used to prepare well-defined nanostructured polymeric materials. This review, with more 650 references illustrates the range of well-defined functional nanomaterials that can be accessed using RAFT chemistry. The detailed syntheses of macromolecules with predetermined molecular weights, designed molecular weight distributions, controlled topology, composition and functionality are presented. RAFT polymerization has been exploited to prepare complex molecular architectures, such as stars, blocks and gradient copolymers. The self-assembly of RAFT-polymer architectures has yielded complex nanomaterials or in combination with other nanostructures has generated hybrid multifunctional nanomaterials, such as polymer-functionalized nanotubes, graphenes, and inorganic nanoparticles. Finally nanostructured surfaces have been described using the self-organization of polymer films or by the utilization of polymer brushes.

“…[1][2][3][4] In particular, it has been pointed out that using remendable adhesives, also as coatings, would lead to better recycling, especially for vehicles' end-of-life or electronic waste. Indeed they are irreversibly cured into a highly cross-linked network giving an infusible and insoluble material.…”

This study describes the synthesis and polymerization of a dicyclocarbonate Diels-Alder (DA) adduct to give a thermoresponsive non-isocyanate polyurethane (NIPU). Firstly a model adduct was synthesized by DA reaction between N-methylmaleimide and furfuryl cyclocarbonate ether (FCE). This adduct was characterized by 1 H-NMR and its thermal behavior was studied by 1 H-NMR, and differential scanning calorimetry (DSC). Then a telechelic dicyclocarbonate DA adduct was obtained by DA reaction between a bismaleimide oligomer and FCE in bulk with full conversion. Its thermal behavior was studied by thermogravimetric analysis (TGA) and DSC. The dicyclocarbonate adduct was polymerized by step-growth polymerization with a diamine, Jeffamine EDR148. The polymerization was performed at room temperature (in order to avoid adduct deprotection) with triazabicyclodecene as the catalyst. The obtained polymer was characterized by size exclusion chromatography (SEC) and 1 H-NMR. The polymer thermal behavior was fully characterized by three complementary analyses. By DSC, retro-Diels-Alder temperatures could be measured to be 90-120°C. By a 1 H-NMR kinetic study at 100°C, it could be shown that after 120 min at 100°C, 85% of the adducts are deprotected. Finally, by SEC, it was demonstrated that the obtained NIPU polymer chains undergo thermal scission by rDA reaction.Scheme 2 Furfuryl cyclocarbonate ether (FCE) synthesis.Scheme 3 Model adduct synthesis by DA reaction between FCE and N-methylmaleimide.
