Abstract
POLIOLES DE POLIMERO DE MUY BAJA VISCOSIDAD CON ELEVADAS RELACIONES ESTIRENO/ACRILONITRILO Y BUENA ESTABILIDAD SE OBTIENEN POR UN PROCESO QUE COMPRENDE LA POLIMERIZACION, MEDIANTE UNA REACCION DE RADICAL LIBRE, UN COMPONENTE MONOMERO, EN LA PRESENCIA DE UNA MEZCLA POLIOL COMPRENDIENDO UNA PORCION MAYOR DE UN POLIOL BASE NO MODIFICADO CON RESINA EPOXI Y UNA PORCION MENOR DE UN POLIOL MODIFICADO CON RESINA EPOXI COMO UN DISPERSANTE. LOS POLIOLES MODIFICADOS CON RESINA EPOXI UTILES COMO DISPERSANTES PUEDEN SER HECHOS POR REACCION DE UN INICIALIZADOR POLIOL CON UNA FUNCIONALIDAD DE H ACTIVO DE 3 A 8 Y UNO O MAS OXIDOS DE ALQUILENO CON UNA RESINA DE POLIOL BASE MODIFICADO CON RESINA EPOXI SEA CARGADO INICIALMENTE AL REACTOR, JUNTO CON PARTE DEL POLIOL BASE.
