Abstract

METODO DE PRODUCCION DE POLIMEROS LIQUIDOS TERMINADOS EN MERCAPTANO. CONSISTE EN CALENTAR UN POLIMERO LIQUIDO TERMINADO EN MERCAPTANO, QUE CONTIENE 0,5 A 3% DE COMPUESTOS MERCAPTANICOS, DE PESO MOLECULAR INFERIOR A 300 Y TIENEN OLOR DESAGRADABLE, A UNA TEMPERATURA COMPRENDIDA ENTRE 115JC Y 135JC DURANTE MENOS DE 2 MINUTOS, DE MODO QUE SE VAPORICE AL MENOS EL 50% DE DICHOS COMPUESTOS, SIN QUE SE DESCOMPONGA EL POLIMERO; Y SEPARAR LOS VAPORES DE COMPUESTOS MERCAPTANICOS DE BAJO PESO MOLECULAR DEL POLIMERO LIQUIDO. ESTOS POLIMEROS TIENEN APLICACIONES PARA FORMAR COMPUESTOS OBTURADORES ELASTOMEROS, SOLIDOS.
