    摘要： An edible body composed of a cellulose having a crystal form of cellulose II, which is regenerated from an aqueous solution of an alkali metal hydroxide, and at least one guest component selected from polypeptides and edible polysaccharides. The cellulose II or a homogeneous mixture of the cellulose II and polysaccharide is present in the form of a sea component or a continuous phase in an amount of at least 10% based on the edible body. The edible body is made by adding at least one guest component selected from polypeptides, polysaccharides and living body constituents composed mainly thereof to an alkali solution in which up to 50 parts by weight of an undissolved cellulose is swollen and dispersed per 100 parts by weight of a dissolved cellulose, directly or after dissolution in an aqueous solution of an alkali, to form a dope in which at least 50% by weight of the total guest component is dissolved, extruding the dope through an extruder, coagulating the extrudate, and neutralizing, water-washing and, if necessary, drying the extrudate.

    摘要： 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.

    摘要： A process for producing fire retardant phosphonitrilate polymers by reacting phosphonitrilic halide with a hydroxyl compound such as an aliphatic or aromatic alcohol at not more than about 40.degree.C in the presence of an acid acceptor, such as pyridine, under conditions such that a relatively low concentration of the hydroxyl compound is present during the initial 1/2 to 3 hours of the reaction and the reaction conditions are maintained at from 20.degree.-50.degree.C for a period of 1/2 to 120 hours and, optionally, further heating the reaction mixture to a temperature of 40.degree.-80.degree.C for 1/2 to 81/2 hours. The phosphonitrilate polymers are suitable for fire retarding cellulosic materials such as regenerated cellulose, rayon and the like.
