Current research and development status and prospect of hot-melt adhesives / Li, Wen in Industrial & engineering chemistry research, Vol. 47 N°20 (Octobre 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 N°20 (Octobre 2008) . - P. 7524-7532 Titre : Current research and development status and prospect of hot-melt adhesives : a review Type de document : texte imprimé Auteurs : Li, Wen, Editeur scientifique ; Laziz Bouzidi, Editeur scientifique ; Suresh S. Narine, Editeur scientifique Année de publication : 2008 Article en page(s) : P. 7524-7532 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Hot-melt  adhesives  (HMAs) Résumé : Fundamental characteristics, general physical and mechanical behavior, and the recent developments in the knowledge of hot-melt adhesives (HMAs) are introduced. The current research and development status for HMAs is reviewed, with an emphasis on the development of new types/generations of HMAs. In particular, some crucial issues and challenges on the technological improvements and the materials development are discussed. On the basis of the current predicted shortage of energy resources and environmental concerns, prospective research on the development of green HMAs is suggested.

Lubricating and waxy esters II / Laziz Bouzidi in Industrial & engineering chemistry research, Vol. 51 N° 45 (Novembre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 45 (Novembre 2012) . - pp. 14892-14902 Titre : Lubricating and waxy esters II : Synthesis, crystallization, and melt behavior of branched monoesters Type de document : texte imprimé Auteurs : Laziz Bouzidi, Auteur ; Shaojun Li, Auteur ; Steve Di Biase, Auteur Année de publication : 2013 Article en page(s) : pp. 14892-14902 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Crystallization Résumé : A comprehensive study of branched derivatives of four pure jojoba wax-like esters (JLEs), having 36, 40 (two isomers), and 44 carbons was conducted to elucidate their crystallization and melting behavior. Crystallization and melting characteristics depended strongly on the number of branches, molar mass, and symmetry. The derivatives demonstrated a very strong tendency to form glassy liquids rather than crystal phases and remain liquid-like at very low temperatures. As the number of branches increased, their crystallinity decreased drastically while their glassy phase increased concomitantly with the depression of the onset of crystallization and/or glass transition temperature. A variety of possible transformation paths, ranging from very little polymorphic activity to extremely polymorphic behavior, depending on number of branches, mass, and symmetry were revealed. It is shown that asymmetry plays a large role in the low temperature behavior, rendering the branched derivatives of the asymmetrical JLEs much better candidates for lubricant formulations.
