Abstract
SE PREPARAN POLIESTERES DE ACIDO GRASO DE POLIOL QUE TIENEN UNA ESTABILIDAD OXIDANTE MEJORADA USANDO LA ADICION DE UN MATERIAL ALCALINO A LOS POLIESTERES DE ACIDO GRASO DE POLIOL CRUDOS SINTETIZADO ANTES DE CONDUCIRLOS AL ACABADO DEL CRUDO. EL MATERIAL ALCALINO SE AÑADE EN UNA CANTIDAD TAL QUE EL PRODUCTO ACABADO TIENE UN PH DE APROXIMADAMENTE 6.0 A APROXIMADAMENTE 8.5.
