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 ... -
El puzzle como actividad de evaluación en el aula en grupos numerosos
(Institut de Ciències de l'Educació (ICE), 2010)
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 ... -

(2014-10-01)
Article
Accés obertThis work presents an analysis of the assessment tools used by professors at the Universitat Politécnica de Catalunya to assess the generic competencies introduced in the Bachelor’s Degrees in Engineering. In order to ... -
New epoxy thermosets modified with amphiphilic multiarm star polymers as toughness enhancer
(2014-10-01)
Article
Accés restringit per política de l'editorialThe synthesis and characterization of two novel amphiphilic multiarm star polymers with linear polyethylene glycol (PEG) and poly(s-caprolactone) (PCL) arms and their use as toughening modifiers of epoxy anhydride thermosets ... -

(2014-09-15)
Article
Accés restringit per política de l'editorialHyperstar polymers (HSPs) with hyperbranched aromatic polyester core and arms consisting of block copolymers of poly(methyl methacrylate) and poly(hydroxyethyl methacrylate) have been used as polymeric modifiers in ... -
Novel epoxy-silica hybrid coatings by using ethoxysilyl-modified hyperbranched poly(ethyleneimine) with improved scratch resistance
(Elsevier, 2014-09-26)
Article
Accés restringit per política de l'editorialA new hyperbranched poly(ethyleneimine) with ethoxysilyl groups at the chain ends has been synthesized and characterized and then used in epoxy formulations to generate new organic/inorganic hybrid materials. Formulations ... -
Effect of hydroxyl ended and end-capped multiarm star polymers on the curing process and mechanical characteristics of epoxy/anhydride thermosets
(2014-08-01)
Article
Accés restringit per política de l'editorialMultiarm star polymers have been synthesized by cationic ring-opening polymerization of epsilon-caprolactone from a hyperbranched poly(ethyleneimine) core and end-capped with acetic anhydride. These star polymers have been ...
