Abstract

"MéTODO PARA TRATAMENTO DE UMA MISTURA QUE CONTENHA CELULOSE, MéTODO INTEGRADO PARA A PRODUçãO DE POLPA DE CELULOSE ESPECIAL, MISTURA TRATADA QUE CONTéM CELULOSE, BEM COMO USO DA REFERIDA MISTURA". A presente invenção refere-se a um método para o tratamento de uma mistura que contém celulose, que compreende pelo menos uma etapa de adição de pelo menos um agente capaz da redução de grupos carbonila. A invenção também refere-se a uma polpa de celulose especial, obtida através de um método que compreende o referido tratamento. Além disso, a invenção refere-se a utilização da polpa de celulose especial de acordo com a invenção ou da polpa de celulose especial obtida através de um método de acordo com a invenção para a produção de derivados da celulose ou de materiais que contenham moléculas de celulose, incluindo, porém não limitados a éteres de celulose ou ésteres de celulose. Os derivados da celulose obtidos a partir da polpa de celulose especial de acordo com a invenção exibem uma viscosidade aumentada elou uma capacidade de brilho aumentada sobre derivados de celulose obtidos a partir de polpa de celulose especial não submetida ao tratamento da invenção.
