Fecha de publicación: | 8-dic-2006 | Editor: | Elsevier | Citación: | Polymer 47(26): 8420-8429 (2006) | Resumen: | A new convenient route for the synthesis of poly(-caprolactone) (PCL) with α,ω-telechelic diols' end-groups is presented. Synthesis of α,ω-telechelic PCL diols (HOPCLOH) was achieved by ring-opening polymerization (ROP) of -caprolactone (CL) catalyzed with ammonium decamolybdate (NH4)8[Mo10O34] and using diethylene glycol (DEG) as initiator. Obtained HOPCLOH was characterized by 1H and 13C NMR, FT-IR, GPC and MALDI-TOF. Comparative studies demonstrate that ammonium decamolybdate (NH4)8[Mo10O34] is better catalyst than Sn-octanoate (SnOct2) toward CL polymerization in presence of DEG, under the conditions tested. A biodegradable poly(ester-urethane-urea) derivative was efficiently prepared from synthesized HOPCLOH. Obtained polymer shows minor differences with respect to the properties recorded for a poly(ester-urethane-urea) obtained from commercial HOPCLOH. | Descripción: | 10 páginas, 8 figuras, 2 esquemas, 4 tablas. | Versión del editor: | http://dx.doi.org/10.1016/j.polymer.2006.10.023 | URI: | http://hdl.handle.net/10261/34252 | DOI: | 10.1016/j.polymer.2006.10.023 | ISSN: | 0032-3861 |
