Abstract

Una mejora en el proceso para producir polímeros pegajosos en un reactor de lecho fluidizado catalizado mediante un catalizador de metal de transición, en presencia de un material de partículas inerte que tiende a generar cargas negativas excesivas en el reactor, llevando a cabo el proceso en presencia de una composición que comprende una mezcla de una sal de fosfato de alcohol y una sal de amonio cuaternario, que se disuelve en un solvente apropiado.
