Abstract
POLIéTER POLIOIS BASEADOS NO LìQUIDO DA CASTANHA DE CAJU, UM PROCESSO PARA A PRODUçãO DESTES POLIéTER POLIÈIS, ESPUMAS FLEXìVEIS PRODUZIDAS DESTES POLIéTER POLIóIS, E UM PROCESSO PARA A PRODUçãO DESTAS ESPUMAS. A presente invenção refere-se a poiléter polióis que são preparados por alcoxilação de materiais de fonte renovável, e particularmente liquido de casca de castanha de caju (LCC), e a um processo para a preparação destes poliéter polióis. Esta invenção também refere-se a espumas de poliuretano flexíveis preparadas a partir destes poliéter polióis de cadeia longa, e a um processo para a produção destas espumas flexíveis de poliuretano.POLYETER POLYES BASED ON CASHEWBERRY LIQUID, A PROCESS FOR THE PRODUCTION OF THESE POLYETER POLYES, FLEXIBLE FOAM PRODUCED FROM THESE POLYETER POLYES, AND A PROCESS FOR THE PRODUCTION OF THESE FOAMS. The present invention relates to polyether polyols which are prepared by alkoxylation of renewable source materials, and particularly cashew nut shell (LCC) liquid, and to a process for the preparation of these polyether polyols. This invention also relates to flexible polyurethane foams prepared from these long chain polyether polyols, and to a process for producing these flexible polyurethane foams.
