  • Tubular casings
    Patent number: 4788087
    Abstract: Tubular packaging casing, in particular a food-stuffs casing of regenerated cellulose, which contains an internal coating of film-forming plastic resins, which contains 10 to 200 mg of a protein coagulant per m.sup.2 of internal coating having at least one COOH-group or a salt thereof.
    Type: Grant
    Filed: May 28, 1987

  • Process for the production of hydroxyalkyl methyl celluloses
    Patent number: 4508895
    Abstract: A process for the production of water-soluble hydroxyalkyl methyl cellulose by the alkalization of the cellulose with sodium hydroxide and by subsequent etherification with alkylene oxide in an inert solvent, characterized in that before etherification, the alkali content of the aqueous alkali cellulose is reduced to 0.3-0.8 mols of NaOH/mol of cellulose by washing out with a suitable, known solvent (mixture), and is then etherified with an alkylene oxide in the liquid phase.
