Thermodynamic Analysis of the Phase Separation during the Polymerization of a Thermoset System into a Thermoplastic Matrix. I. Effect of the Composition on the Cloud-Point Curves
(John Wiley & Sons Inc, 2004-04)
The cloud‐point curves of polystyrene (PS) mixed with reactive epoxy monomers based on diglycidyl ether of bisphenol A with stoichiometric amounts of 4,4′‐methylenebis(2,6‐diethylaniline) were experimentally studied. A ...
Thermodynamic Analysis of the Phase Separation during the Polymerization of a Thermoset System into a Thermoplastic Matrix. II. Prediction of the Phase Composition and the Volume Fraction of the Dispersed Phase
(John Wiley & Sons Inc, 2004-04)
A thermodynamic simulation of the phase‐separation process of an off‐critical blend, based on a thermoplastic matrix with a reactive epoxy system undergoing polycondensation at a constant temperature, was performed. The ...
Smart and sustainable design of latent catalyst-containing benzoxazine-bio-resins and application studies
(Royal Society of Chemistry, 2020-02)
A straightforward synthetic approach to incorporate a hydrogen-bonding motif as part of a fully biobased benzoxazine monomer (NAR-fa) is developed, leading to the first latent catalyst-containing thermosetting resin derived ...
Mechanical properties of linseed oil monoglyceride maleate/styrene copolymers
(John Wiley & Sons Inc, 2005-08)
In this study, rigid thermoset polymers were prepared from radical copolymerization of linseed oil monoglyceride maleates with styrene (St). First, linseed oil monoglycerides (LOMGs) were obtained from the reaction of ...
From spherical micelles to hexagonally packed cylinders: the cure cycle determines nanostructures generated in block copolymer/ epoxy blends
(American Chemical Society, 2013-06-04)
Block copolymer (BCP)/epoxy blends have been intensively investigated during the past decade. Macrophase separation of the BCP in the cured thermoset is avoided by selecting one block that is initially immiscible or that ...
Nanostructured epoxies based on the self-assembly of block copolymers: A new miscible block that can be tailored to different epoxy formulations
(American Chemical Society, 2007-02)
Nanostructured thermosets may be obtained by the self-assembly of amphiphilic block copolymers (BCP) in a reactive solvent and fixation of the resulting morphologies by the cross-linking reaction. Nanostructuration requires ...
Remote actuation of epoxy nanocomposites with functional properties
(Asociación Química Argentina, 2018-10)
Las redes epoxi son una familia de compuestos con uso extensivo en aplicaciones tales comorecubrimientos, adhesivos y materiales compuestos avanzados. Exhiben diferentes propiedadesfuncionales tales como la capacidad de ...
Thermal degradation of a phenolic resin, vegetable fibers, and derived composites
(John Wiley & Sons Inc, 2008-03)
The thermal degradation behavior of resol, several vegetable fibers (two types of cotton fibers, sisal and sugar cane bagasse) and derived polymer composites have been investigated using thermogravimetric analysis (TGA). ...
Direct relationships between volume variations at macro and nanoscale in epoxy systems. PALS/PVT measurements
(Elsevier, 2004-12)
The free volume in epoxy systems fully cured with aminic hardeners having different chemical structures was studied by means of positron annihilation lifetimes spectroscopy. The results are compared with those obtained ...
