Abstract

Patente de Invenção: <B>"PROCESSO PARA PREPARAçãO DE POLIETERPOLIóIS DE CADEIA LONGA LIVRE DE REPROCESSAMENTO"<D>. A invenção refere-se a um processo para preparação de polieterpolióis de cadeia longa livre de reprocessamento, pelo qual primeiramente, por catálise com sulfonatos de perfluoralquila de metais do grupo III A da tabela periódica dos elementos (relativo à convenção IUPAC de 1970) de iniciadores de baixo peso molecular por reação com óxidos de alquileno a temperaturas de reação de 80 até 200°C e concentrações de catalisador de 5 até 200 ppm, são obtidos compostos de partida alcoxilados oligoméricos, com pesos moleculares entre 200 e 1000, que em seguida são reagidos livre de reprocessamento e separação de catalisador por meio de catalisadores de DMC altamente ativos a uma concentração de catalisador de 30 ppm ou menos, relativo à quantidade do polieterpoliol a ser preparado por reação com óxidos de alquileno de alto peso molecular, são obtidos polieterpolióis de cadeia longa.
