Abstract
Un procedimiento y su correspondiente recipiente de reacción de polimerización para eliminar sustancialmente la acumulación de polímeros sobre las superficies internas de dicho recipiente cuyo procedimiento comprende: a) hacer reaccionar, i) el productos auto-condensación de un fenol poli-hídrico, o ii) el producto de condensación de dos o más fenoles poli-hídricos o iii) el producto de auto- condensación de un naftol poli-hídrico con un agente blanqueante para formar un oligómero de estructura general **fórmula** donde R es H o OH, R'' es O o un enlace C-C , R''` es H o Cl, R''`'' está seleccionado del grupo formado por O, un enlace C-C, un enlace C-H y n es un número entero de 1 a 10, b) preparar una disolución acuosa alcalina de revestimiento con el oligómero obtenido en la etapa anterior y aplicarlo a las superficies internas del recipiente de polimerización y c) realizar la reacción de polimerización del monómero (s) mientras esta en contacto con las superficies internas revestidas de dicho recipiente.
