Abstract
A shaped article, especially a tubing, is disclosed which comprises a plasticized cellulose hydrate composition comprising a cellulose hydrate and a plasticity enhancing amount of at least one substantially water insoluble plasticizing ester of an aliphatic monocarboxylic acid containing from about 9 to about 24 carbon atoms and a polyalcohol comprising at least two hydroxy groups at least one of which is esterified with said aliphatic monocarboxylic acid, and water and/or a plasticizer. Such shaped articles can be prepared by mixing a viscose solution with a liquid containing the plasticizing ester, introducing the resulting mixture into a precipitating bath and drying the precipitated shaped body. Tube-shaped articles are especially suited as sausage casings.
