  • Patent number: 4367309
    Abstract: Highly stable glycoprotein derivative compositions showing little tendency to decrease in physiological activity thereof are produced by reacting an aldehyde-group-containing glycoprotein (A) with an SH- or OH-containing material (B), and if necessary further reacting the resulting product with an SH- or OH-containing material of the same or another kind. They are used as diagnostic reagents or hydrolytic catalysts.

  • Patent number: 4365060
    Abstract: The invention provides a novel enterosoluble capsule for containing a medicament, which is shaped with a hitherto not used novel cellulose derivative. The cellulose derivative is a mixed ester of an alkyl-, hydroxyalkyl- or hydroxyalkyl alkylcellulose esterified with succinyl anhydride and an aliphatic monocarboxylic acid anhydride. The enterosoluble capsules have excellent enterosolubility behavior as well as sufficient pliability even without the addition of a plasticizer which is almost indispensable in the prior art materials. The cellulose derivative can be shaped into capsules not only by the conventional dipping method but also by the plastic deformation at an elevated temperature under pressure such as compression molding, vacuum forming, matchedmold forming and the like.

  • Patent number: 4359047
    Abstract: A gelatinous adhesive composition and a tacky article of manufacture are produced by heating at least one polyhydric alcohol and at least one material selected from the group consisting of naturally occurring high molecular weight polysaccharide gums, other than gum Karaya, and resins which are a copolymer of a vinyl ether and a second component selected from maleic anhydride and its corresponding free acid, together in the absence of solvent to promote chemical reaction between the components and to drive off water produced in the reaction, the reaction being carried substantially to completion. In another embodiment, the components are at least one polyhydric alcohol, a resin which is a copolymer of a vinyl ether and a second component selected from maleic anhydride and its corresponding free acid, and a material selected from the group consisting of gelatin and naturally occurring high molecular weight polysaccharide gums.

  • Patent number: 4356819
    Abstract: An article of manufacture with adhesive properties comprising a gelatinous adhesive composition dispersed in a plastics matrix. The gelatinous adhesive composition is the resulting product of heating together in the absence of solvent at least one polyhydric alcohol and at least one material selected from the group consisting of gelatin, naturally occurring high molecular weight polysaccharide gums, and resins which are a copolymer of a vinyl ether and a second component selected from organic acid anhydrides and their corresponding free acids. Heating promotes a chemical reaction between the components and also drives off water produced in the reaction which is carried substantially to completion.
