ABSTRACT:
A shaped article, especially a tubing, is disclosed which comprises a plasticized cellulose hydrate composition of high mechanical strength which is obtained by treating a plasticized cellulose composition obtained by treating cellulose 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-tetra-methylol, alkylamino-bis-dimethylene-triazinone-tetra-methylol and a substantially water insoluble ester of an aliphatic monocarboxylic acid containing from about 9 to about 25 carbon atoms and a polyalcohol, such as glycerol or polyethylene glycol, with a synthetic polymer containing recurring oxyalkylene units and at least one, preferably at least two, terminal N-methylolcarbamate groups, and water and/or 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 synthetic polymer and drying it in the heat. Tube shaped articles are especially suited as sausage casings.
