Abstract

"PROCESSO PARA PREPARAR POLIéTER POLIóIS E POLIóIS PREPARADOS COM ESTES". Poliéter polióis adequados para uso na preparação de espumas de poliuretano rígidas são preparados por um processo utilizando catalisadores de imidazol. Os catalisadores de imidazol não perdem reatividade a altas temperaturas e podem ser usados a temperaturas mais altas para preparar polióis decrescendo assim o tempo de residência e o consumo de energia em processos de produção de polióis.
