Effect of orotic acid on the crystallization kinetics and morphology of biodegradable poly (l-lactide) as an efficient nucleating agent / Zhaobin Qiu in Industrial & engineering chemistry research, Vol. 50 N° 21 (Novembre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 21 (Novembre 2011) . - pp. 12299-12303 Titre : Effect of orotic acid on the crystallization kinetics and morphology of biodegradable poly (l-lactide) as an efficient nucleating agent Type de document : texte imprimé Auteurs : Zhaobin Qiu, Auteur ; Zhisheng Li, Auteur Année de publication : 2011 Article en page(s) : pp. 12299-12303 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Morphology  Kinetics  Crystallization Résumé : The wider practical application of biodegradable and biocompatible poly(L-lactic acid) (PLLA) has been restricted because of many disadvantages, especially its relatively slow crystallisation rate. In this note, a PLLA/orotic add (OA) composite was prepared via a simple melt compounding method. It is found that both the nonisothermal melt crystallization and overall isothermal melt crystallization kinetics of PLLA have been enhanced signifcantly in the composite, even at very low OA content, relative to that of neat PLLA, indicating that OA is an efficient muleating agent of PLLA for its wider practical application, especially as biomaterial.
