A statistical design of experiments for optimizing the MALDI-TOF-MS sample preparation of polymers. An application in the assessment of the thermo-mechanical degradation mechanisms of poly (ethylene terephthalate)

Badía Valiente, José David; Strömberg, Emma Marie; Ribes Greus, María Desamparados; Karlsson, Sigbritt (ELSEVIER SCIENCE BV, 2011)

[EN] The sample preparation procedure for MALDI-TOF MS of polymers is addressed in this study by the application of a statistical Design of Experiments (DoE). Industrial poly (ethylene terephthalate) (PET) was chosen as ...
Analytical strategies for the quality assessment of recycled high-impact polystyrene (HIPS)

Vilaplana Domingo, Francisco Javier (Universitat Politècnica de València, 2008-05-30)

Polymers are subjected to physical and chemical changes during their processing, service life, and further recovery, and they may also interact with impurities that can alter their composition. These changes substantially ...
Assessing the MALDI-TOF MS sample preparation procedure to analyze the influence of thermo-oxidative ageing and thermo-mechanical degradation on poly (Lactide)

Badia, J.D.; Strömberg, Emma Marie; Ribes Greus, María Desamparados; Karlsson, Sigbritt (Elsevier, 2011)

[EN] Multiple processing by means of successive injection cycles was used to simulate the thermo-mechanical degradation effects on the oligomeric distribution of PLA under mechanical recycling. Likewise, an accelerated ...
Assessing the MALDI-TOF MS sample preparation procedure to characterize the thermo-mechanical degradation mechanisms of plastics for packaging

Badía Valiente, José David (Universitat Politècnica de València, 2016-02-15)

In the present study, the general aim is to assess the MALDI-TOF MS sample preparation procedure, in order to characterize the thermo-mecanical degradation mechanisms of two polyesters used in the packaging industry: the ...
Correlation of chemical, structural and thermal properties of naturalfibres for their sustainable exploitation

Moriana Torró, Rosana; Vilaplana Domingo, Francisco Javier; Karlsson, Sigbritt; Ribes Greus, María Desamparados (Elsevier, 2014-11-04)

The potential of lignocellulosic natural fibres as renewable resources for thermal conversion and material reinforcement is largely dependent on the correlation between their chemical composition, crystalline structure ...

Improved thermo-mechanical properties by the addition of natural fibres in starch-based sustainable biocomposites

Moriana Torró, Rosana; Vilaplana, Francisco; Karlsson, Sigbritt; Ribes Greus, A. (Elsevier, 2011)

Sustainable biocomposites based on thermoplastic starch copolymers (Mater-Bi KE03B1) and biofibres (cotton, hemp and kenaf) were prepared and characterised in terms of their thermo-mechanical and morphological properties. ...
Material valorisation of amorphous polylactide. Influence of thermo-mechanical degradation on the morphology, segmental dynamics, thermal and mechanical performance

Badía Valiente, José David; Strömberg, Emma; Karlsson, Sigbritt; Ribes Greus, A. (ELSEVIER SCI LTD, 2012-04)

[EN] This paper reports the effects of multiple mechanical recycling on the structure and properties of amorphous polylactide (PLA). The influence of the thermo-mechanical degradation induced by means of five successive ...
Nmr relaxation reveals modifications in rubber phase dynamics during long-term degradation of high-impact polystyrene (HIPS)

Vilaplana, Francisco; Karlsson, Sigbritt; Ribes-Greus, A.; Schade, Christian; Nestle, Nikolaus (ELSEVIER SCI LTD, 2011)

[EN] The microstructure of rubber-modified polystyrene after thermal ageing at 90 °C and multiple extrusion was analyzed by time-domain nuclear magnetic resonance (TD-NMR) in a non-destructive manner. The transverse ...
Optimisation of sampling procedires for the identification of octa-BDE in recycled styrenic samples from waste electrical and electronic equipment
