New epoxy thermosets modified with multiarm star poly(lactide) with poly(ethyleneimine) as core of different molecular weight
(2013-08)
Article
Accés restringit per política de l'editorialMultiarm stars containing a hyperbranched poly(ethyleneimine) core of different molecular weight and poly(lactide) arms were synthesized by cationic ring-opening polymerization of lactide from a hyperbranched poly(ethyleneimine) ... -
Assessment tasks: center of the learning process
(2012-05-01)
Article
Accés restringit per política de l'editorialAssessment is at the centre of learning process, and is what therefore determinates the process of teaching-learning. It is because of this, the assessment tasks must be designed with several criteria which guarantee its ... -
A new epoxy based layered silicate nanocomposite using a hyperbranched polymer: study of the curing reaction and nanostructure development
(2013)
Comunicació de congrés
Accés restringit per política de l'editorialPolymer layered silicate (PLS) nanocomposites based on epoxy resins have been widely studied previously [1], but the anticipated dramatic enhancement of their properties has not yet been realised. One approach to overcoming ... -

Comunicació de congrés
Accés obertLa presente comunicación expone cómo se ha utilizado la técnica del puzle como actividad de evaluación en el aula con el doble objetivo de realizar una evaluación continua e introducir la competencia de l trabajo en ... -
New catalysts for diglycidyl ether of bisphenol A curing based on thiol-epoxy click reaction
(2014-10-01)
Article
Accés restringit per política de l'editorialThe thiol-epoxy click reaction has been employed in the curing of diglycidyl ether of bisphenol A (DGEBA) using latent amine precursors in ratios of 0.5 and 2 phr. The kinetics of the curing of mixtures of DGEBA/thiol/amine ... -
Thermal analysis of polymer layered silicate nanocomposites. Identification of nanostructure development by DSC
(2014-11-01)
Article
Accés restringit per política de l'editorialIt has been shown, for three different polymer layered silicate (PLS) nanocomposite systems, how differential scanning calorimetry (DSC) can identify the different reactions of homopolymerisation and of crosslinking that ... -
