Inexpensive and readily available Ce2O3 and CeO2 catalyzed ring-opening polymerization of lactone
Stable and inexpensive catalysts are particularly important in the catalysis industry. This study investigated cheap stable Ce2O3 and CeO2 as catalysts for the ring-opening polymerization of rac-lactide (rac-LA) and ε-caprolactone (ε-CL). Both Ce2O3 and CeO2 effectively catalyzed the polymerization of lactones. The catalytic efficiency of Ce2O3 was significantly higher than that of CeO2. The catalytic polymerization process was carried out under controlled conditions, and narrow molecular-weight distributions of polylactide and polycaprolactone were obtained. A kinetic study of the catalytic polymerization of rac-LA showed that the polymerization conformed to first-order kinetics and was controllable.
期刊介绍：
Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology.
As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including:
polymer synthesis;
polymer reactions;
polymerization kinetics;
polymer physics;
morphology;
structure-property relationships;
polymer analysis and characterization;
physical and mechanical properties;
electrical and optical properties;
polymer processing and rheology;
application of polymers;
supramolecular science of polymers;
polymer composites.
