Abstract

UN PROCEDIMIENTO PARA PREPARAR UNA DISPERSION DE POLIMERO EN UNA FASE CONTINUA DE POLIOL, QUE COMPRENDE FORMAR UN DISPERSANTE HOMOPOLIMEARIZANDO UN ADUCTO TERMINADO EN VINILO O COPOLIMERIZANDO DICHO ADUCTO CON UN MONOMERO O MEZCLA DE MONOMEROS ETILENICAMENTE INSATURADOS, EN PRESENCIA DE UN COMPUESTO QUE CONTIENE HIDROGENO ACTIVO COMO DISOLVENTE, SIENDO EL DISPERSANTE RESULTANTE SOLUBLE EN UN POLIOL DE BASE Y TENIENDO UNA VISCOSIDAD BROOKFIELD MENOR QUE 25.000 CENTIPOISES EN SOLUCION AL 20-35% EN PESO EN UN COMPUESTO QUE CONTIENE HIDROGENO ACTIVO, Y POLIMERIZAR UN MONOMERO O MEZCLA DE MONOMEROS ETILENICAMENTE INSATURADOS EN PRESENCIA DE DICHO DISPERSANTE Y UN POLIOL DE BASE DE MANERA QUE EL MONOMERO POLIMERIZADO FORME PARTICULAS ESTABILIZADAS CONTRA AGLOMERACION POR EL DISPERSANTE. EL POLIOL POLIMERO OBTENIDO TIENE UNA VISCOSIDAD SORPRENDENTEMENTE BAJA Y ES ESPECIALMENTE UTIL PARA FORMULAR ESPUMAS DE POLIURETANO.
