Abstract

PROCEDIMIENTO PARA LA OBTENCION DE (CO)POLIMERIZADOS DE ESTIRENO EN SUSPENSION, MEDIANTE POLIMERIZACION DE MONOMEROS A BASE DE ESTIRENO, QUE CONTIENEN POLIMERIZADOS DE SUSPENSION DE ESTIRENOS DISUELTOS, EN PRESENCIA DE ESTABILIZADOR DE SUSPENSION. CONSISTE EN DISPERSAR LA FASE DE MONOMERO, ANTES DE INICIAR LA POLIMERIZACION, DURANTE 15 A 120 MINUTOS A TEMPERATURAS COMPRENDIDAS ENTRE 10 C Y 80 C, MIENTRAS SE AGITA, EN UNA FASE ACUOSA QUE CONTIENE UN ACIDO MINERAL DISUELTO, EN PRESENCIA DE UN FOSFATO DE METAL POCO SOLUBLE, TAL COMO FOSFATO CALCICO, COMO ESTABILIZADOR. TIENE APLICACIONES PARA OBTENER COPOLIMERIZADOS DE VINILPIRROLIDONA, ACIDO ACRILICO, ALCOHOLES POLIVINILICOS Y ETERES DE CELULOSA.
