Synthesis of thermoresponsive oligo(ethylene glycol) polymers through radical ring-opening polymerization of vinylcyclopropane monomers

Abstract

Polyvinylcyclopropanes are designed to exhibit a thermally triggered aggregation process in aqueous solutions.

Molecular bases for temperature sensitivity in supramolecular assemblies and their applications as thermoresponsive soft materials

“…For pendant polymers, ether-pendant, including ones with OEG sidechains, can also cause LCST-type response in polymers regardless of their backbone chemistry. [81][82][83] Similar to the previous examples, the LCST behavior of polymers with OEG sidechain originates from the combination of hydrophobic alkyl backbones and hydrophilic OEG sidechain. The LCST of these polymers are also influenced by OEG length alteration.…”

Synthesis of reactive polyureas bearing vinylcyclopropane moiety in main chain and their radical cross‐linking with multifunctional thiols

“…Vinylcyclopropanes (VCPs) with two radical-stabilizing groups (cyano, [1][2][3][4] ester, [2][3][4][5][6][7] and amide [8,9] ) undergo radical ring-opening polymerization (RROP) to yield polymers with C C bonds in main chains. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] As shown in Scheme 1a, the vinyl group of VCP derivative reacts with radical species. After that, the resulting radical will be transformed into an acyclic radical species via the preferential cleavage of C1-C2 bond on VCP moiety.…”
