Abstract

SE OBTIENE UN COPOLIMERO DE INJERTO, INJERTANDO, POR UN MECANISMO DE REACCION POR RADICALES LIBRES EN DISOLUCION ACUOSA, MATERIAL MONOMERO ETILENICAMENTE INSATURADO SOLUBLE EN AGUA EN GRUPOS HIDROXILO QUE TIENEN SUBSTRATOS SOLUBLES EN AGUA, Y SE FORMAN SOBRE EL SUBSTRATO RADICALES LIBRES USANDO UN METAL OXIDANTE CAPAZ DE SER REDUCIDO POR EL SUBSTRATO A UN ESTADO DE VALENCIA INFERIOR, POR EJEMPLO CERIO, Y PERSULFATO U OTRO COMPUESTO PEROXI CAPAZ DE OXIDAR EL METAL DE NUEVO AL ESTADO DE VALENCIA SUPERIOR. EL PROCESO SE LLEVA A CABO PREFERIBLEMENTE COMO UN PROCESO DE POLIMERIZACION EN FASE INVERSA, Y LA INVENCION INCLUYE TAMBIEN UNA NUEVA EMULSION DE FASE INVERSA QUE CONSTA DE UNA DISPERSION DE PARTICULAS DE POLIMERO DE FASE INVERSA DE UN COPOLIMERO DE INJERTO DE CARBOXIMETILCELULOSA, DEXTRANO O ALMIDON CON ACRILAMIDA Y ACIDO ACRILICO Y/O AMPS.
