Abstract

Los catalizadores de polimerizacion de cianuro metálico están soportados sobre una zeolita que es capaz de entrar en reacciones de cambio de cationes. Loscatalizadores soportados son catalizadores de polimerizacion activos para oxidos de alquileno. Son separados fácilmente del producto de polimerizacion yreciclados. Se utilizan para la polimerizacion de oxidos de alquileno.The metal cyanide polymerization catalysts are supported on a zeolite that is capable of entering cation exchange reactions. Supported catalysts are active polymerization catalysts for alkylene oxides. They are easily separated from the polymerization product and recycled. They are used for the polymerization of alkylene oxides.
