Improved synthesis of bis(chloromethyl)arene monomers
(Vsp Bv, 2005-12)
We report here on the experimental conditions for radical chlorination that provide improved yields of 2,5-bis(chloromethyl) pyridine and pyrazine, as well as on theoretical calculations which were performed in order to ...
Tetramethyl guanidine-assisted synthesis and thermal crosslinking of multifunctional benzoxazine monomers based on natural phloretic acid
(John Wiley & Sons Inc, 2021-09)
An efficient strategy to synthesize novel biobased multifunctional benzoxazine compounds was developed using the 1,1,3,3-tetramethyl guanidine (TMG)-triggered esterification of natural phloretic acid with organic halides ...
Aquaporins: More than functional monomers in a tetrameric arrangement
(MDPI, 2018-11)
Aquaporins (AQPs) function as tetrameric structures in which each monomer has its ownpermeable pathway. The combination of structural biology, molecular dynamics simulations, andexperimental approaches has contributed to ...
Synthesis of a metal chelating monomer for radiation polymer dosimetry
(Pergamon-Elsevier Science Ltd, 2021-03)
To enhance the performance of polymeric dosimeters it is necessary to design novel formulations considering the mechanisms that register the absorbed dose (e.g. induced polymerization) and the readout method. The combination ...
Synergism between Terbinafine and a Neo-clerodane Dimer or a Monomer Isolated from Baccharis flabellata against Trichophyton rubrum
(Natural Products, 2019-01)
The new neo-clerodane dimer (DACD) likely formed by a [4+2] photo-cycloaddition between two molecules of ent-15,16-epoxy-19-hydroxy-1,3,13(16),14-clerodatetraen-18-oic acid (DAC), both isolated from Baccharis flabellata ...
Magnetic field effects on the copolymerization of water-soluble and ionic monomers
(John Wiley & Sons Inc, 2009-01)
The effect of magnetic field (MF) on the radical copolymerization of a series of water-soluble and ionic monomers is presented including acrylamide (AM), acrylic acid (AA), its ionized form acrylate (A-), and diallyldime ...
Thermodynamic analysis of a polymerization-induced phase separation in nanoparticle-monomer-polymer blends
(American Chemical Society, 2007-10-04)
We perform a thermodynamic analysis of the polymerization-induced phase separation in nanoparticle-monomer-polymer blends using a simple model recently proposed by Ginzburg (Macromolecules 2005, 38, 2362). The model was ...
Limit of Applicability of the Monomer-Enhanced Mechanism for Radical Generation in Persulfate Initiated Polymerization of Acrylamide
(Planta Piloto de Ingeniería Química, 2010-10)
The limit of applicability of the monomer-enhanced mechanism as dominant mechanism ruling the initiation process of the polymerization of acrylamide (AM) initiated with potassium persulfate (K2S2O8) has been determined. ...
Multiphase Equilibria Modeling of Fast Pyrolysis Bio-Oils: Group Contribution Associating Equation of State Extension to Lignin Monomers and Derivatives
(American Chemical Society, 2019-05)
Fast pyrolysis is a promising route to using biomass as a source of renewable energy and chemicals. For economic feasibility, this process has to be optimized with regard to product yield and handling. One of the big ...
Theoretical and experimental vibrational spectrum study of 4-hydroxybenzoic acid as monomer and dimer
(Pergamon-Elsevier Science Ltd, 2010-05)
Theoretical calculations on the molecular geometry and the vibrational spectrum of 4-hydroxybenzoic acid were carried out by the Density Functional Theory (DFT/B3LYP) method. In addition, IR and Raman spectra of the ...
