Abstract
La presente invención se refiere a un metodo para impedir la formación de escamas de polímero en un recipiente de polimerización, durante la polimerización de un monómero que tiene un enlace doble etilenicamente, en que la polimerización de un monómero que tiene enlace doble etilenicamente, en que la polimerización se lleva a cabo en un recipiente de polimerización en el cual la superficie de pared interna se ha revestido previamente con una solución de revestimiento a base de agua, que contiene (A) un tinte aniónico soluble en agua y (B) al menos un miembro selecionado del grupo que consta de tintes catiónicos insolubles en agua, con un pH de 7 o menos, y luego se secan para formar un revestimiento.
