Abstract

LA PRESENTE INVENCION SE RELACIONA CON COPOLIMEROS DE POLIETER CON UNA GRADO BAJO DE POLIMERIZACION (3, 4) QUE PROPORCIONA EL CONTROL PARA LAS ESPUMAS GENERADAS POR LOS AGENTES SUPERFICIATIVOS BASADOS EN ORGANOSILICONA EN AGUA SIN LA NECESIDAD DE UN COMPONENTE ANTIESPUMA ADICIONAL. EL AGENTE DE CONTROL DE ESPUMA COPOLIMERICO ES UN COMPUESTO DE LA FORMULA: EN LA QUE X+Y = 1-2, Y >/- 1, R{SUP,1} ES UN GRUPO ALQUILENOXIDO DE LA FORMULA C{SUB,A}H{SUB,2A}O(C{SUB,3}H{SUB,6}O){SUB,Z}R{SUP,2} EN DONDE A=3-4, Z ES 1-15, R{SUP,2} ES HIDROGENO, UN RADICAL DE HIDROCARBONO DE ENTRE 1 Y 4 CARBONOS O ACETIL. ESTA INVENCION PROPORCIONA UNAS COMPOSICIONES PARA SU UTILIZACION EN LAS FORMULACIONES AGRICOLAS QUE DAN UN CONTROL DE ESPUMA MEJORADO PARA ESPUMAS GENERADAS A PARTIR DE AGENTES SUPERFICIATIVOS DE ORGANOSILICONA EN SISTEMAS ACUOSOS. EL AGENTE DE CONTROL DE ESPUMA COPOLIMERICO ES SOLUBLE EN UNA MATRIZ DE UN AGENTE SUPERFICIATIVO QUE CONSTA DE UN AGENTE SUPERFICIATIVO DE ORGANOSILICONA SOLO O EN MEZCLASCON AGENTES SUPERFICIATIVOS CONVENCIONALES DE CADENA CORTA. ESTA INVENCION PROPORCIONA UNAS FORMULACIONES AGRICULTURALES DE BAJA FORMACION DE ESPUMA, HOMOGENEAS Y CLARAS QUE TIENEN UN AGENTE DE CONTROL DE ESPUMA COPOLIMERICA INDISOLUBLE EN AGUA, Y UNOS ALCOXILADOS DE TRISILOXANA O TETRASILOXANA SOLUBLES O DISPERSABLES EN AGUA CUANDO SE UTILIZA ESTA FORMULACION EN UNA MEZCLA ACUOSA.
