Abstract
Un procedimiento para eliminar sustancialmente la acumulación de polímeros sobre las superficies internas de un reactor de polimerización para ser utilizado en sistemas de polimerización en emulsión que comprende la aplicación a dichas superficies de una solución de recubrimiento consistente en una solución en disolvente orgánico que contiene un producto de condensación sin neutralizar seleccionado del grupo que consiste en (1) el producto de autocondensación de un fenol polihidroxílico, (2) el producto de condensación de dos o más fenoles polihidroxílico y (3) el producto de autocondensación de un naftol polihidroxílico donde dicho(s) fenol(es) polihidroxílico(s) se selecciona(n) entre el grupo que consiste en resorcina, hidroquinona, catequina y floroglucina, secando la citada solución de recubrimiento sobre las citadas superficies para producir un recubrimiento sobre las mismas con un espesor en el intervalo de aproximadamente 5 micras a aproximadamente 50 micras, y polimerizando en emulsión uno o más monómeros etilénicamente no saturados polimerizables mientras están en contacto con dicho recubrimiento.
