Abstract

"DERIVADOS DE CELULOSE COM PROPRIEDADES REOLóGICAS SEMELHANTES A GEL E PROCESSO PARA PRODUçãO DOS MESMOS". A invenção descreve éteres de celulose com propriedades reológicas semelhantes a gel em solução aquosa, obtenível pelo fato de que a) alcaliniza-se celulose com solução de hidróxido alcalino aquosa, na presença de um agente de suspensão, b) deixa-se a celulose alcalinizada reagir com um ou mais óxidos de alquileno, c) depois, reage-se com um halogeneto de alquila contido no agente de suspensão, d) subseq³entemente ou simultaneamente, reage-se a celulose alcalinizada com um reticulador, em uma quantidade de 0,0001 a 0,05 eq sendo que a unidade 'eq' representa a relação molar do reticulador com relação à unidade de anidroglicose (AGU) da celulose usada, e e) após, opcionalmente, adição adicional de hidróxido alcalino e/ou agente de alcalinização, o derivado de celulose obtido, irreversivelmente reticulado, é separado da mistura de reação, opcionalmente purificado e seco.
