Terminal relaxation of model poly(dimethylsiloxane) networks with pendant chains
(American Chemical Society, 2001-06)
Stress relaxation of model poly(dimethylsiloxane) networks with pendant chains and nearly constant cross-linking density was studied. The networks were obtained by end-linking a mixture of long chains bearing terminal ...
Comparison of Mean-Field Theory and 1 H NMR Transversal Relaxation of Poly(dimethylsiloxane) Networks
(American Chemical Society, 2001-01)
We have estimated the mass fraction of elastic and pendant chains of model poly- (dimethylsiloxane) (PDMS) networks using transverse proton relaxation in nuclear magnetic resonance (1H NMR). These experiments were compared ...
Dynamic response of transiently trapped entanglements in polymer networks
(Elsevier, 2014-02)
The structure and viscoelastic response of polymer networks are highly sensitive to the presence of pendant chains. These imperfections, that are unavoidable produced during a cross-linking reaction, reduce the cross-linking ...
Transiently trapped entanglements in model polymer networks
(American Chemical Society, 2009-06)
The relaxational dynamics of trapped entanglements in model silicone polymer networks is studied through the residual dipolar couplings (RDC) obtained by double quantum nuclear magnetic resonance (DQ NMR). These experiments ...
Characterization of terpolymers containing 1,2,4-oxadiazolic pendant groups with potential application as workover fluids
(John Wiley & Sons Inc, 2011-03)
Presence of planar, bulky heterocyclic pendant groups, attached to polymer chains, alters the thermal properties and, once gelled, they modify their rheological properties as well. The authors report generation of stiff ...
Self-assembly of a bridged silsesquioxane containing a pendant hydrophobic chain in the organic bridge
(American Chemical Society, 2007-03)
The aim of this study was to synthesize and characterize the self-assembly of a new family of bridged silsesquioxanes containing a pendant hydrophobic chain in the organic bridge. The precursor of this hybrid was obtained ...
Pyridine derivative covalently bonded on chitosan pendant chains for textile dye removal
(Elsevier Sci LtdOxfordInglaterra, 2014)
Photochemical cross-linking study of polymers containing diacetylene groups in their main chain and azobenzene compounds as pendant groups
(Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C., 2016)
Dispersion of gold dodecanthiolate in a silsesquioxane film with pendant dodecyl chains: from photoluminescent materials to gold nanocomposites
(Springer, 2013-08-27)
Photoluminescence of Au(I)-dodecane thiolate (Au(I)-DDT) and its thermal reduction to metallic gold have been extensively reported in the literature. But incorporation of this salt to a polymeric matrix to produce ...
