Thermally Promoted Elimination and Substitution Reactions in Poly(p-arylene vinylene) Precursor Polyelectrolytes
(American Chemical Society, 2000-06)
The thermal conversion of dialkylsulfonium polyelectrolyte precursor polymers 1b-e to poly(p-arylene vinylene)s was studied by direct pyrolysis mass spectrometry in order to elucidate the mechanism of the sulfonium elimination ...
Diffusion kinetics at liquid-glassy polymer interphases
(Wiley VCH Verlag, 2005-04)
We explored the diffusion mechanisms in a series of liquid/glassy polymer interphases. The diffusion experiments were performed in a unique way: the temperature range studied encompassed the glass transition temperature ...
3D Nanostructured Conjugated Polymers for Optical Applications
(Wiley VCH Verlag, 2015-11)
The self assembly of block-copolymers into the gyroid morphology is replicated into 3D nanostructured conjugated polymers. Voided styrenic gyroidal networks are used as scaffolds for the electrodeposition of two ...
Liquid-glassy polymer diffusion: Effects of liquid molecular weight and temperature
(Wiley VCH Verlag, 2007-05)
We examine mechanistic aspects of the diffusion between a series of liquid polystyrenes (PS) and a glassy poly(phenylene oxide) (PPO) matrix, through the use of confocal Raman microspectroscopy. The results show that the ...
Self-healable polymer networks based on the cross-linking of epoxidised soybean oil by an aqueous citric acid solution
(Royal Society Of Chemistry, 2013-09-09)
Epoxidised soybean oil (ESO) was cross-linked with an aqueous citric acid (CA) solution without the addition of any other catalyst or solvent. Completely bio-based polymer networks were generated. The initial system was ...
Liquid-Glassy Polymer Interphases: Diffusion Kinetics in Conditions of Unlimited Liquid Supply
(Wiley VCH Verlag, 2009-03)
We investigate evidences of diffusion controlled by mechanical relaxation of the glassy matrix, i.e. Case-II mechanism, in a series of liquid/glassy interphases formed by polystyrene (PS) and poly (phenylene oxide) (PPO) ...
PC-SAFT equation: A predictive tool to determine experimental conditions for polymer blend demixing
(Taylor & Francis, 2009-08-06)
The perturbed-chain statistical associating fluid theory equation of state (PC-SAFT) was applied to predict the phase behavior of polymer solutions in order to determine the pressure - temperature region for the high ...
Synthesis and characterization of dendronized polymers
(Wiley, 2007-11)
This research aims at the synthesis of several dendrons with different functional groups on their surface, and their use as functionalizing agents of synthetic polymers. Two principal products were synthesized and ...
Kinetics and binding properties of cloramphenicol imprinted polymers
(Elsevier Science, 2007-04)
Molecularly imprinted polymers (MIPs) are easily obtained by a non-covalent approach through the copolymerisation of suitable functional monomers and cross-linkers in the presence of the print molecule. Removal of the ...
Thermo-sensitive polymers in medicine: A review
(Pergamon-Elsevier Science Ltd, 2019-08)
A wide variety of smart polymer systems such as thermosensitive polymers (TSPs)have been developed and applied mimicking nature. TSPs are a class of macromolecules that exhibit bio-inspired behavior and have various ...
