Abstract

Patente de Invenção: "PROCESSO PARA A PREPARAçãO DE POLIéTER-POLIóIS". A invenção refere-se a um processo para a preparação de poliéter-polióis por meio de catálise de cianeto de metal duplo (DMC), no qual a fase de indução é nitidamente reduzida. Pela dosagem contínua de um óxido de alquileno na mistura de iniciador-catalisador pode ser obtida uma redução essencial da fase de indução em comparação com a ativação às bateladas.
