Abstract

LA INVENCION SE REFIERE A SUSTANCIAS UTILES COMO ADITIVOS REDUCTORES DE AGUA Y PLASTIFICANTES PARA COMPOSICIONES DE CEMENTO. DICHAS SUSTANCIAS SE FORMAN A PARTIR DE LA REACCION DE POLIMEROS DE ACIDO CARBOXILICO CON UN POLIETER, PREFERIBLEMENTE CON UNA MEZCLA DE POLIETERES MONOFUNCIONALES Y DIFUNCIONALES, DERIVADOS DE EPOXIDOS C 2 - C 4 , LOGRANDOSE UNA ESCISION PARCIAL DE LOS POLIETERES Y UNA ESTERIFICACION PARCIAL DE LOS POLIETERES Y DE LOS PRODUCTOS DE ESCISION DE LOS MISMOS, PRODUCIDAS POR EL OTRO REACTIVO. EN UNA REALIZACION DE LA INVENCION, SE UTILIZA UN ACIDO SULFONICO PARA CATALIZAR LA REACCION DE POLI (ACIDO ACRILICO), UN COPOLIMERO DE OXIDO DE ETILENO MONOFUNCIONAL - OXIDO DE PROPILENO, Y UN POLI (PROPILEN GLICOL) DIFUNCIONAL, A UNA TEMPERATURA EN EXCESO DE 140 (GRADOS) C.
