Abstract
UN METODO PARA REDUCIR EL OLOR DE UNA RESINA DE ETER DE POLIFERILERO QUE CONSISTE EN AÑADIR UN ACIDO CARBOXILICO O ANHIDRIDO O ACIDO CARBONICO A LA RESINA DE ETER DE POLIFENILENO DURANTE LA FUSION QUE COMPRENDE LA RESINA DE ETER DE POLIFENILENO Y VAPOR QUE LIMPIA LA RESINA DE ETER DE POLIFENILENO. EL ACIDO CARBOXILICO O EL ANHIDRIDO SE PUEDEN AÑADIR EN ESTADO SOLIDO PERO PREFERENTEMENTE SE AÑADEN EN UNA SOLUCION ACUOSA. EL ACIDO CARBOXILICO SE AÑADE PREFERENTEMENTE ES UNA SOLUCCION ACUOSA. UN ACIDO PREFERENTE ES EL ACIDO CITRICO. UNA RESINA DE POLIESTIRENO SE PUEDE MEZCLAR CON LA RESINA DE ETER DE POLIFENILENO PARA FORMAR UNA COMPOSICION MEZCLADA.
