Abstract
PROCEDIMIENTO PARA FABRICAR POLIMERIZADOS ALCOXILADOS CONTENIENDO GRUPOS CARBOXILOS Y (B) EN MEDIO ACUOSO Y A UNA TEMPERATURA DE 120 C. LA TRANSFORMACION SE REALIZA CON UN PH INICIAL ENTRE 5,0 Y 5,9 Y UN PH FINAL ENTRE 5,5, Y 8,5. SEGUN EL CONTROL DEL VALOR DE PH SE MEJORA LA SELECTIVIDAD DE LA ADICION DE ALQUILENOXIDO EN EL PROCEDIMIENTO CONOCIDO FRENTE A LA UTILIZACION DEL POLIMERIZADO (A). SIENDO (A) POLIMERIZADO QUE CONTIENE UN ACIDO CARBONICO UNIPOLIMERIZADO INSATURADO MONOETILENO CON TRES A SEIS CARBONOS Y (B) ALQUILENOXIDOS.
