Abstract
Agentes supresores de la acumulación que comprendenproductos de condensación entre un aldehido, un compuesto de fenol y un ácido carboxílico aromático hidroxilado en el núcleo aromático.Un proceso para la preparación de un agente supresor de la acumulación de acuerdo con cualquiera de las reivindicaciones 1 a 5, que comprende reaccionar el aldehido, el compuesto fenólico y el ácido carboxílico aromático hidroxilado en el núcleo aromático en presencia de un agente alcalino fuerte, a una temperatura que oscila entre 40 y 120°C, durante un período de tiempo que oscila entre 1 y 8 horas.Una composición que tiene actividad anti acumulación que contiene uno o más de los agentes supresores de la acumulación de acuerdo con cualquiera de las reivindicaciones 1, 2, 3, 4 ó 5 y un vehículo adecuado.Los agentes supresores de la acumulación de acuerdo con cualquiera de las reivindicaciones 1, 2, 3, 4 ó 5 empleados en un proceso de polimerización de cloruro de vinilo o acetato de vinilo o de mezclas de los mismos, en presencia o ausencia de otros monómeros o polímeros polimerizados con los mismos.
