Abstract
PROCEDIMIENTO PARA LA OBTENCION DE DISPERSIONES ACUOSAS DE POLIACRILATO CON MEJOR COMPORTAMIENTO DE FLUJO. CONSISTE EN POLIMERIZAR ESTERES ACRILICOS Y/O ESTERES METACRILICOS DE ALCANOLES QUE CONTIENEN DE 1 A 10 ATOMOS DE CARBONO, CON 0 A 60% EN PESO DE ESTIRENO Y/O 0 A 20% EN PESO DE ESTERES VINILICOS Y/O 0 A 10% EN PESO DE COMONOMEROS MONOOLEFINICAMENTE INSATURADOS, EN EMULSION ACUOSA A 30 A 95 C, MIENTRAS SE AGREGA UNA EMULSION DE MONOMEROS EN PRESENCIA DE INICIADORES DE POLIMERIZACION CONVENCIONALES DE RADICALES LIBRES, COLOIDES PROTECTORES, DE 0,5 A 5% EN PESO DE EMULSIFICANTES NO IONICOS Y EVENTUALMENTE REGULADORES; AL MENOS SE AÑADE UNA PARTE DEL COLOIDE PROTECTOR Y/O DE UN ACIDO MONOCARBOXILICO Y/O DICARBOXILICO MONOOLEFINICAMENTE INSATURADO DURANTE LA ENTRADA DE LOS MONOMEROS EN CANTIDADES CRECIENTES POR UNIDAD DE TIEMPO, A LA MEZCLA DE POLIMERIZACION.
