Abstract

Patente de Invenção: <B>"PROCESSO PARA A PREPARAçãO DE POLIóIS DE POLIéTERES"<D>. Os polióis de poliéteres podem ser preparados reagindo-se polióis com epóxidos na presença de catalisadores básicos, tratando-se os polióis de poliéteres que contém os catalisadores básicos com compostos sólidos com OH funcional de metais dos grupos de III a VIII do sistema periódico dos elementos (Mendeleyev), os ditos compostos sendo insolúveis nos polióis de poliéteres e apresentando áreas superficiais de BET de 10 a 1.000 m^ 2^/g, isolando-se os compostos inorgânicos sólidos carregados com os catalisadores básicos do poliol de poliéter e usando-se os mesmos na reação de polióis com epóxidos ou colocando-se os compostos inorgânicos isolados carregados com os catalisadores básicos em contato com os polióis que devem ser usados na reação com os epóxidos, separando-se aqueles polióis dos compostos inorgânicos e distribuíndo-os para a reação com epóxidos.
