ABSTRACT OF THE DISCLOSURE A shaped article, especially a tubing, is disclosed which comprises a plasticized cellulose hydrate composition of high mechanical strength which is obtained by reacting a plasticized cellulose composition obtained by treating cellu- lose hydrate with a plasticity-enhancing amount of at least one plasticizing alkyl derivative which comprises an alkyl containing from about 8 to about 24 carbon atoms and which is selected from'the group consisting of alkylamido-bis- dimethylene-triazinone-tetramethylol, a substantially water insoluble ester of an aliphatic monocarboxylic acid contain- ing from about 9 to about 25 carbon atoms, and a polyalcohol, such as glycerol or polyethylene glycol with a cyclic dimethylolurea derivative, and water and/or a plasticizer. Such shaped articles can be prepared by mixing a viscose solution with a liquid containing the plasticizing alkyl derivative, introducing the resulting mixture into a precipitating bath, washing the precipitated shaped body in the gel state, treating it with an acidic solution of the cyclic urea compound and drying it in the heat. Tube-shaped articles are especially suited as sausage casings.
