Abstract

Patente de Invenção: <B>"PROCESSO APERFEIçOADO DE POLIMERIZAçãO DE EPóXIDOS"<D>. A quantidade de impurezas de alto peso molecular presentes em um poliéter poliol produzido por meio de alcoxilação de um iniciador contendo hidrogênio ativo usando um epóxido tal como óxido de propileno e um catalisador de complexo de cianeto de metal duplo altamente ativo substancialmente amorfo pode ser vantajosamente diminuída tendo um ácido de Lewis não prótico presente durante a polimerização do epóxido. O uso de haletos tais como cloreto de zinco e cloreto de alumínio é especialmente eficaz para tais propósitos. Em uma modalidade preferencial, também estão presentes quantidades menores de água durante a polimerização. Os poliéter polióis de pureza superior produzidos deste modo são particularmente úteis na preparação de espumas de poliuretano em chapas e moldadas, as quais tendem a quebrar ou se tornar excessivamente rígidas quando estão presentes níveis elevados de cauda de alto peso molecular no poliéter poliol.
