Title
(PT) Processo para a produção de corpos celulósicos moldados
Abstract
(PT)
"PROCESSO PARA A PRODUçãO DE CORPOS CELULóSICOS MOLDADOS". A presente invenção refere-se a um processo para a produção de corpos moldados celulósicos de acordo com o processo de óxido de amina, que compreende as etapas a seguir: - moldagem de uma solução de celulose em um óxido de amina terciária aquoso - precipitação da solução moldada - lavagem do corpo moldado assim obtido e - secagem do corpo moldado. O processo de acordo com a invenção é caracterizado pelo fato de que é adicionado um polímero de quitossónio à solução da celulose e/ou a um precursor da dita solução e/ou o corpo moldado é tratado com um polímero de quitossónio antes da secagem, com o polímero de quitossónio sendo essencialmente completamente solúvel em um ativador padronizado.
