Crystallization behavior of reactive blends between PBS and PA6IcoT / Kun Cao in Industrial & engineering chemistry research, Vol. 51 N° 15 (Avril 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 15 (Avril 2012) . - pp. 5461-5468 Titre : Crystallization behavior of reactive blends between PBS and PA6IcoT Type de document : texte imprimé Auteurs : Kun Cao, Auteur ; Qiang Wang, Auteur ; Ya-chan Zhou, Auteur Année de publication : 2012 Article en page(s) : pp. 5461-5468 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Crystallization Résumé : A biodegradable crystalline aliphatic polyester, poly(butylene succinate) (PBS), and an amorphous semiaromatic nylon, poly(hexamethylene isophthalamide-co-terephthalamide) (PA6IcoT), were melted and reactively blended with p-toluene sulfonic acid as the catalyst. The isothermal and nonisothermal crystallization processes of PBS and its blends with PA6IcoT were investigated by differential scanning calorimetry (DSC). Three different models (Jeziorny’s, Ozawa’s, and Mo et al.’s methods) were used to simulate the isothermal and nonisothermal crystallization kinetics. Moreover, the crystalline morphologies were observed by polarized optical microscopy. The effects of PA6IcoT and the ester–amide exchange reaction between polyester and polyamide on the crystallization processes and crystalline morphology are described in detail.
