Epoxy networks containing large mass fractions of a monofunctional Polyhedral Oligomeric Silsesquioxane (POSS)
(American Chemical Society, 2003-05)
A polyhedral oligomeric silsesquioxane (POSS) containing one epoxy group and seven isobutyl groups per molecule was incorporated into an epoxy network following a two-stage process. In the first stage, POSS was reacted ...
Epoxy networks modified by multifunctional polyhedral oligomeric silsesquioxanes (POSS) containing amine groups
(Springer, 2008-07)
The hydrolytic condensation of a precursor synthesized by the reaction of equimolar amounts of (3-aminopropyl)triethoxysilane and phenylglycidylether led to a distribution of polyhedral oligomeric silsesquioxanes (POSS) ...
Properties of epoxy networks derived from the reaction of diglycidyl ether of bisphenol a with polyhedral oligomeric silsesquioxanes bearing OH-functionalized organic substituants
(John Wiley & Sons Inc, 2003-07-01)
A polyhedral oligomeric silsesquioxane (POSS), consisting mainly of a mixture of octahedra, nonahedra, and decahedra with bulky and flexible organic sub-stituents, with three secondary hydroxyls per organic group, was used ...
A Polyhedral Oligomeric Silsesquioxane (POSS) Doped with Cerium(III) / Fe(II) and its Application as an Electrochemical Sensor for L-dopamine
(2022-01-01)
A Polyhedral oligomeric silsesquioxane (POSS) doped with cerium (III) was synthesized and reacted with potassium hexacyanoferrate (SCeH). The vibrational, structural, morphological and electrochemical properties of this ...
Poly(silsesquioxanes) derived from the hydrolytic condensation of organotrialkoxysilanes containing hydroxyl groups
(Elsevier Science Sa, 2003-12)
Organotrialkoxysilanes containing secondary hydroxyl groups were synthesized by reacting 1 mole of (3-aminopropyl)triethoxysilane (APS) with 1 or 2 mole of phenylglycidylether (PGE). Resulting products, APS-PGE and APS-PGE2, ...
Metallocene supported on a polyhedral oligomeric silsesquioxane‐modified silica with high catalytic activity for ethylene polymerization
(2005)
A polyhedral oligomeric silsesquioxane (POSS) consisting of a mixture of perfect and imperfect polyhedra with 8–10 Si atoms bonded to bulky and branched organic groups functionalized with (β‐hydroxy)‐tertiary amines, was ...
Monofunctional epoxy-POSS dispersed in epoxy - Amine networks: Effect of a prereaction on the morphology and crystallinity of POSS domains
(American Chemical Society, 2007-02)
Several studies have recently reported the use of monofunctional octahedral oligomeric silsesquioxanes (monofunctional POSS) to modify polymer networks. In most of these studies the final material is depicted as a network ...
Synthesis, characterization and catalytic application of a new organometallic oligomer based on polyhedral oligomeric silsesquioxane
(2017-10-01)
Although homogeneous catalysts provide high performance and selectivity, the difficulty of separation and recycling of these catalysts has bothered the scientific community worldwide. Therefore, the demand for heterogeneous ...
Marginal integrity of restorations produced with a model composite based on polyhedral oligomeric silsesquioxane (POSS)
(Univ Sao Paulo Fac Odontologia Bauru, 2015-09-01)
Marginal integrity is one of the most crucial aspects involved in the clinical longevity of resin composite restorations. Objective: To analyze the marginal integrity of restorations produced with a model composite based ...
