Abstract

PROCEDIMIENTO PARA LA PRODUCCION DE UN POLIOL POLIMERO FLUIDO. CONSISTE EN POLIMERIZAR UNO O MAS MONOMEROS, COMO ESTIRENO Y ACETONITRILO, EN UN POLIOL LIQUIDO, CUYA VISCOSIDAD ES INFERIOR A 10.000 CENTIPOISES A TEMPERATURA AMBIENTE, Y CUYO INDICE HIDROXILO ES DE 10 A 150, SIN SATURACION ADICIONAL, EN PRESENCIA DE UN CATALIZADOR DE RADICALES LIBRES, COMO UN COMPUESTO DE PEROXIDICARBONATO, A UNA TEMPERATURA DE 100 A 300JC. SIENDO EL POLIOL POLIMERO FLUIDO DEL TIPO QUE COMPRENDE MAS DE UN 30% EN PESO DE UN POLIMERO DERIVADO DE LOS MONOMEROS Y MENOS DE UN 70% EN PESO DEL POLIOL LIQUIDO, Y TENIENDO UNA FILTRABILIDAD, A TRAVES DE UN TAMIZ DE MALLA 700, SUPERIOR AL 10% EN 300 SEGUNDOS. SE USA EN LA INDUSTRIA QUIMICA PARA FABRICAR POLIURETANO, ESPUMAS, ELASTOMEROS, RESINAS Y FIBRAS.
