Abstract

QUE COMPRENDE: a) FUNDIR Y HOMOGENEIZAR EN UN REACTOR DE AGITACION, LOS COMPONENTES DE LA REACCION; b) TRANSFERIR LA MEZCLA DE REACCION A VARIOS RECIPIENTES DE MENOR VOLUMEN, DONDE SE TERMINA DE POLIMERIZAR DICHA MEZCLA; Y, c) AISLAR EL POLIESTER OBTENIDO, RETIRANDOLO DE LOS RECIPIENTES. EL POLIESTER RESORBIBLE ES UNA POLILACTIDA O UN POLIGLICOLIDO, UN COPOLIMERO DE GLICOLIDO Y CARBONATO DE TRIMETILENO, COPOLIMERO DE LACTIDA Y GLICOLIDO, COPOLIMERO DE LACTIDA Y CARBONATO DE TRIMETILENO, COPOLIMERO DE LACTIDA Y E-CAPROLACTONA, O UN TERPOLIMERO. LOS RECIPIENTES DE MENOR VOLUMEN SON DE UNA POLIOLEFINA, O SE COMPONEN DE UN POLIMERO FLUORADO
