Abstract

"SOLUçãO RETARDADA DE éTER DE CELULOSE E UM PROCESSO PARA SUA PREPARAçãO". é descrito um processo para preparação de éteres de celulose solúveis de forma retardada em água, abrangendo as etapas de a) tratamento do éter de celulose úmido com uma solução de um dialdeído e b) secagem e trituração do éter de celulose, caracterizado pelo fato de ser introduzida ao éter de celulose concomitantemente, ou juntamente com a solução de dialdeído, uma solução salina aquosa, sendo que o valor do pH do éter de celulose é homogeneamente ajustado ao valor de pH 6,0 até 8,0.
