Enamine-Based Hydrophilic Dynamic Covalent Polymer Networks: Effects of pH, and Copolymer Composition and Concentration on the Aqueous Swelling Degrees and the Gel Formation Times
(2015)
In this work, we explore the formation in water of dynamic covalent polymer networks cross-linked via enamine groups. The polymer networks resulted from the combination of pairs of chemically complementary hydrophilic ...
Synthesis and characterization of reversible and self-healable networks based on acylhydrazone groups
(2014)
A series of seven dynamic covalent networks based on pentaerythritol tetra(benzohydrazide) and 1,10-decanediol dibenzaldehyde were prepared in N,N-dimethylformamide (DMF). The equilibrium degree of swelling in DMF and the ...
Regular and inverse polyampholyte hydrogels: A detailed comparison
(2016)
Two series of polyampholyte (PA) hydrogels were prepared via reversible addition-fragmentation chain transfer polymerization, followed by removal of the protecting group of the acidic monomer repeating units (methacrylic ...
Symmetrical polymer systems prepared using a degradable bifunctional atom transfer radical polymerization initiator: Synthesis, characterization, and cleavage
(2017)
Linear (co)polymers and dimethacrylate-end-linked polymer networks of methyl methacrylate with 2-(dimethylamino)ethyl methacrylate, cleavable in the middle of the polymer chain, either under thermolysis or alkaline hydrolysis ...
A degradable atom transfer radical polymerization inimer: Synthesis, polymerization, and cleavage of the resulting polymer products
(2017)
A novel degradable inimer for atom transfer radical polymerization (ATRP), 2-(6-(2-((2-bromo-2-methylpropanoyl)oxy)ethyl)pyridin-2-yl)ethyl methacrylate (PyDEBrMΑ), was synthesized by the two-step esterification of ...
A dimethacrylate cross-linker cleavable under thermolysis or alkaline hydrolysis conditions: Synthesis, polymerization, and degradation
(2016)
We develop a new platform based on 2,6-pyridinediethanol diesters for introducing polymer degradability under thermolysis or alkaline hydrolysis conditions, with the latter being rare in polymers. Such labile diesters can ...
ABC Triblock Terpolymers with Orthogonally Deprotectable Blocks: Synthesis, Characterization, and Deprotection
(2015)
The development and availability of new protecting groups are vital for all branches of synthetic chemistry. Equally vital is the facile and selective removal of these groups, leaving intact other protecting groups which ...
2-(Pyridin-2-yl)ethanol as a protecting group for carboxylic acids: Chemical and thermal cleavage, and conversion of poly[2-(pyridin-2-yl)ethyl methacrylate] to poly(methacrylic acid)
(2012)
In this communication, we show that 2-(pyridin-2-yl)ethanol is a good protecting group for methacrylic acid (MAA), which can be selectively removed, after polymerization, either chemically under alkaline conditions or ...
Dynamic Covalent Star Poly(ethylene glycol) Model Hydrogels: A New Platform for Mechanically Robust, Multifunctional Materials
(2017)
We develop a new platform of dynamic covalent model polymer networks comprising two types of four-armed star poly(ethylene glycol)s (tetraPEG), one end-functionalized with benzaldehyde groups and the other with ...
