Abstract
Un procedimiento para la preparación de una solución de revestimiento que, aplicada sobre las superficies internas de una vasija de reacción de polimerización permite eliminar sustancialmente la acumulación de polímeros sobre dichas superficies internas y que está constituida por una solución acuosa de un hidróxido de metal alcalino que contiene alrededor de 0,01 a 0,10% en peso de una amina poliaromática de cadena lineal o ramificada, con un peso molecular superior a 250 aproximadamente, conteniendo como mínimo dos grupos -OH por cada 1000 unidades de peso molecular y alrededor de 0,002 a 0,02% en peso de un dispersante en medios acuosos, y opcionalmente un antioxidante, siendo la relación de dicha amina poliaromática a dicho dispersante de 10:1 a 2:1 aproximadamente.
