  • Publication number: 20100289177
    Abstract: The present invention relates to a process for the production of cellulosic moulded bodies according to the amine-oxide process, comprising the following steps: moulding a solution of cellulose in an aqueous tertiary amine oxide precipitating the moulded solution washing the moulded body thus obtained and drying the moulded body. The process according to the invention is characterized in that a chitosonium polymer is added to the solution of the cellulose and/or to a precursor of said solution and/or the moulded body is treated with a chitosonium polymer prior to drying, with the chitosonium polymer being essentially completely soluble in a standard dope.
