Tensile properties of polyproylene fibres
Chapitre d'ouvrage scientifique
As soon as it appeared on the market, one half century ago, polypropylene (PP) appeared as a promising fibre-forming polymer but with some difficulties in processing due to a lack of control of its viscoelastic properties and in durability due to its low stability to oxidation. These difficulties were progressively resolved in the last decades by a sharper control of synthesis conditions e.g. of stereoregularity and molar mass distribution, and by a better knowledge of oxidation and stabilization mechanisms. These research efforts allowed PP to invade a very wide range of fibre applications, from disposable diapers to geotextiles.

New insights in polymer-biofuels interaction Avancées dans la compréhension des interactions polymères-biocarburants Article dans une revue avec comité de lectureDJOUANI, Fatma; VERDU, Jacques; FLACONNECHE, Bruno; FAYOLLE, Bruno; RICHAUD, Emmanuel (Institut Français du Pétrole, 2015)This paper deals with polymer-fuel interaction focusing on specific effects of biofuels on polyethylene (PE) in automotive applications. The practical objective is to develop a predictable approach for durability of ...
Article dans une revue avec comité de lectureThis article deals with polypropylene stabilization by hindered 2,6-di-tert-butylphenols. Two aspects are mainly considered: the influence of stabilizer structure, of its concentration and temperature on induction period ...
Chapitre d'ouvrage scientifiquePolymers having an aromatic backbone polymers have a high mechanical strength and a high modulus. Their aromaticity increases their resistance for use in relatively severe conditions especially in aerospace and nuclear ...
Article dans une revue avec comité de lectureThe thermal oxidation behaviour of polyethylene films stabilized by various weight ratios of organophosphites (Irgafos 168) has been studied at selected temperatures. The duration of the induction period was found to ...
Article dans une revue avec comité de lectureThis work deals with a study of stabilizers loss by extraction in ethanol–cyclohexane mixtures simulating ethanol based biofuels. As theoretically predicted, cyclohexane has an extractive power considerably stronger than ...
