Abstract
Los catalizadores de cianuro de metal se preparan en la presencia de un poliácido orgánico. Los catalizadores activos de polimerizacion de oxido dealquileno se forman teniendo mayores tamanos de partícula que los catalizadores convencionales de cianuro de metal y, por lo tanto se separan más facilmente deun polímero preparado con el catalizador. Los poliácidos orgánicos preferidos son polímeros degradados o no degradados que contienen grupos colgantes carboxiloo carboxilato.
