Abstract

Patente de Invenção: <B>"CATALISADORES COMPLEXO DE CIANETO METáLICO DUPLO TRATADOS COM áCIDO"<D>. A quantidade de impurezas de pesos moleculares elevados presente em um poliol de poliéter produzido pela alcoxilação de um iniciador contendo hidrogênio ativo e por um catalisador do tipo complexo de cianeto metálico duplo altamente ativo e substancialmente não-cristalino pode ser diminuída vantajosamente tratando-se o catalisador antes do uso na polimerização com um ácido prótico. Os ácidos próticos apropriados incluem o ácido fosfórico e o ácido acético. Os polióis de poliéter com purezas superiores produzidos desse modo são particularmente úteis na preparação de espumas de poliuretano modeladas e de prancha, que tendem a colapsar ou a se tornarem excessivamente tensas quando níveis elevados de caudas de pesos moleculares elevados estão presentes no poliol de poliéter.
