Abstract
UNA CANTIDAD DEFINIDA DE PEROXIDO DE HIDROGENO SE USA COMO CATALIZADOR DE UNA POLIMERIZACION, BAJO LA CONDICION DE QUE EXISTE UNA CANTIDAD DEFINIDA DE UNA SUSTANCIA ALCALINA, SOLO UN ACIDO MALEICO O UN COMPONENE MONOMERO COMPUESTO DE ACIDO MALEICO Y EL OTRO MOMOMERO NO SATURADO SOLUBLE EN AGUA SON POLIMERIZABLES EN AGUA, DONDE SE PRODUCE UNA SAL (CO-) POLIMERICA DE ACIDO MALEICO MEJORADA, DICHA SAL OBTENDIA ES SUPERIOR EN BIODEGRADABILIDAD, Y UNA PEQUEÑA CANTIDAD DEL MOMOMERO RESIDUAL ES UTIL COMO DETERGENTE.
