Poly(2‐vinyl pyridine)‐block‐Poly(ethylene oxide) Featuring a Furan Group at the Block Junction—Synthesis and Functionalization

Abstract

Furfuryl glycidyl ether (FGE) represents a highly versatile monomer for the preparation of reversibly cross-linkable nanostructured materials via Diels-Alder reactions. Here, the use of FGE for the mid-chain functionalization of a P2VP-b-PEO diblock copolymer is reported. The material features one furan moiety at the block junction, P2VP68 -FGE-b-PEO390 , which can be subsequently addressed in Diels-Alder reactions using maleimide-functionalized counterparts. The presence of the FGE moiety enables the introduction of dyes as model labels or the formation of hetero-grafted brushes as shell on hybrid Au@Polymer nanoparticles. This renders P2VP68 -FGE-b-PEO390 , a powerful tool for selective functionalization reactions, including the modification of surfaces.

Tuning the self-healing behavior of one-component intrinsic polymers

“…The self-healing properties of the most promising terpolymer P(LMA-co-MIMA-co-FMA) were further investigated by Bose et al [21]. Barthel et al extended the concept to functional block copolymers [22][23][24].…”

Thermally reversible and self‐healing novolac epoxy resins based on Diels–Alder chemistry

“…The temperature‐dependent reversible covalent crosslinking of polymers or block copolymers, such as Diels–Alder chemistry, represents an effective method for the implementation of intrinsic self‐healing into functional materials . Until now, self‐healing polymers based on DA reaction of furan and maleimide, such as multifunctional furan–maleimide, polyketones, polyamides, polyethylenes, polyesters, poly(ɛ‐caprolactone), poly(lactic acid), and polyurethanes have been widely studied . Therefore, there are a large number of interesting possibilities in developing new self‐healing polymers system based on DA reaction.…”

Micellization of Photo-Responsive Block Copolymers

“…Both can be precisely adjusted by molecular parameters such as molar mass, volume fraction of the respective segments, overall architecture, and also segment rigidity (this also includes the presence of crystallizable blocks). Additional elements of control include strategies to influence the self-assembly process itself (“pathway”) [22], or to exploit suitable chemical tools to specifically address individual domains or even the block junction [23,24] between two adjacent segments in block copolymer nanostructures [25,26].…”
