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 ...

Group transfer polymerization of biobased monomers
(2013)This article overviews the work by our Group at the University of Cyprus on the attempted controlled polymerization of several biobased unsaturated esters. These were esters of tiglic acid, itaconic acid, fumaric acid, ...

Multiresponsive polymer conetworks capable of responding to changes in pH, temperature, and magnetic field: Synthesis, characterization, and evaluation of their ability for controlled uptake and release of solutes
(2012)This study deals with the preparation of novel multiresponsive (magnetoresponsive, thermoresponsive and pH-responsive) nanocomposite conetworks consisting of oleic acid-coated magnetite nanoparticles (OA•Fe 3O 4), ...

Reactivation of severely aged commercial three-way catalysts by washing with weak EDTA and oxalic acid solutions
(2007)Ethylene diamine tetraacetic acid (EDTA) which is a well-known reagent for its metal extraction efficiency was studied for the first time towards the improvement of the catalytic activity and oxygen storage and release ...

Synthesis and characterization of anionic amphiphilic model conetworks of 2-butyl-1-octyl-methacrylate and methacrylic acid: Effects of polymer composition and architecture
(2007)Seven amphiphilic conetworks of methacrylic acid (MAA) and a new hydrophobic monomer, 2-butyl-1-octyl-methacrylate (BOMA), were synthesized using group transfer polymerization. The MAA units were introduced via the ...

Synthesis and characterization of rigid functional anionic polyelectrolytes: Block copolymers and star homopolymers
(2012)Seven cyclolinear polymers bearing the tertiary-butyl α- (hydroxymethyl)acrylate (TBHMA) ether dimer were prepared using reversible addition-fragmentation chain transfer (RAFT) polymerization. Of the seven polymers, five ...

Three-step synthesis of ethyl canthinone-3-carboxylates from ethyl 4-bromo-6-methoxy-1,5-naphthyridine-3-carboxylate via a Pd-catalyzed Suzuki-Miyaura coupling and a Cu-catalyzed amidation reaction
(2011)Ethyl canthin-6-one-1-carboxylate (1b) and nine analogues 1c-k were prepared from readily prepared ethyl 4-bromo-6-methoxy-1,5-naphthyridine-3- carboxylate (2b) via a three-step non-classical approach that focused on ...

Well-defined networks with precisely located cleavable sites: Structure optimization and core functionality determination
(2008)A study was conducted to determine the core functionality of well-defined covalent polymer networks with precisely located cleavable sites. Covalent polymer networks consists of chemically interconnected polymer chains ...
