      Accés restringit per política de l'editorial
      The aim of this work was to study the effect of crystallinity degree on the thermal, mechanical, and fracture properties of poly(lactic acid)/organomodified montmorillonite (PLA/OMMT) nanocomposites. Samples with two ...
    • Influence of processing on the ethylene-vinyl alcohol (EVOH) properties: Application of the successive self-nucleation and annealing (SSA) technique 

      Franco Urquiza, Edgar Adrian; Santana Pérez, Orlando Onofre; Gamez Pérez, José; Martínez Benasat, Antonio; Maspoch Rulduà, M. Lluïsa (2010-03)
      Article
      Accés restringit per política de l'editorial
      Films of EVOH copolymers, processed three times by twin-screw extrusion were prepared using a cast-film line. The variation on the melt flow rate (MFR) and rheological behaviour of the films were determined, as well as ...
    • Kinetics of the thermal decomposition of processed poly(lactic acid) 

      Carrasco Alonso, Félix Ángel; Pagès Figueras, Pere; Gamez Pérez, José; Santana Pérez, Orlando Onofre; Maspoch Rulduà, M. Lluïsa (2010-12)
      Article
      Accés restringit per política de l'editorial
      The kinetics of the thermal decomposition of processed poly(lactic acid) has been studied and compared to that of raw material. Processing consisted of two different industrial processes: 1) Injection (with or without ...
