Abstract

PROCEDIMIENTO PARA LA POLIMERIZACION DE NO EQUILIBRIO EN DOS ETAPAS REALIZADAS SIN CATALIZADORES EXTERNOS PARA LA PRODUCCION DE COPOLIMEROS DE POLIESTER. EN LA PRIMERA ETAPA DEL PROCEDIMIENTO SE HACEN REACCIONAR LA MITAD DE LOS GRUPOS CARBOXILO DE UN DIACIDO O DE UN DIANHIDRIDO DE ACIDO EN PROPORCIONES ESTEQUIOMETRICAS CON LA MITAD DE LOS GRUPOS HIDROXILO PARA FORMAR UN PRIMER PRODUCTO DE REACCION. EN LA SEGUNDA ETAPA SE HACE REACCIONAR LA OTRA MITAD DE LOS GRUPOS CARBOXILO DEL PRIMER PRODUCTO DE REACCION EN PROPORCIONES ESTEQUIOMETRICAS CON EL GRUPO HIDROXILO. LA PRIMERA ETAPA SE LLEVA A EFECTO A UNA TEMPERATURA DE UNOS 100 GRADOS Y LA SEGUNDA A UNA TEMPERATURA DE UNOS 200 GRADOS APROXIMADAMENTE.
