Abstract
LOS POLI- EP -CAPROLACTONAS SE PRODUCEN POR POLIMERIZACION CONTINUA DE {EP}-CAPROLACTONA EN MASA FUNDIDA EN UNA PRENSA DE EXTRUSION (EXTRUSION REACTIVA) CON INTERVENCION COMO CEBADOR DE POLIMERIZACION DE TRIALCOXIDOS DE ALUMINIO DE LOS QUE AL MENOS UN RADICAL ALCOXI COMPRENDE ADEMAS EL ATOMO DE OXIGENO CONSTITUTIVO DEL ENLACE ALUMINOXANO (AL-O) AL MENOS OTRO ATOMO DE OXIGENO. VENTAJOSAMENTE, ESTE ATOMO DE OXIGENO ESTA PRESENTE EN FORMA DE UNA FUNCION ESTER O ETER. ESTOS CEBADORES SE PRESENTAN GENERALMENTE EN ESTADO DE LIQUIDO A TEMPERATURA AMBIENTE Y SE PUEDEN POR OTRA PARTE MEZCLAR CON {EP}CAPROLACTONA, DE MANERA QUE PUEDEN SER UTILIZADOS EN AUSENCIA DE SOLVENTE. EL AJUSTE APROPIADO DE LOS CAUDALES DE ALIMENTACION DE LA PRENSA DE EXTRUSION DE {EP}-CAPROLACTONA Y DE CEBADOR PERMITE LA FABRICACION A MODO DE POLI-{EP}-CAPROLACTONAS QUE TIENEN MASAS MOLECULARES MEDIAS EN PESO PREESTABLECIDAS.
