[Class 140] Sheets or films of water-soluble polyvinyl alcohol are provided with a water-resistant heat-sealable coating by treatment with a solution of a water-insoluble polyvinyl-acetal resin, an aliphatic aldehyde of not more than 4 carbon atoms and an acid catalyst, in a volatile solvent, and then heating for a sufficient time to effect solvent removal and to effect reaction between the polyvinyl alcohol and the aldehyde to form a strongly anchored coating on said sheet or film. The coated film may then be washed to remove catalyst and any unreacted aldehyde; and dried. The base sheet or film may be produced from any polyvinyl alcohol which is soluble in water, including incompletely saponified polyvinyl acetate and related esters, and including also polyvinyl alcohols in which part of the alcohol groups have been reacted with aldehydes such as formaldehyde, acetaldehyde,propionaldehyde or butyraldehyde, to form acetal groups. The base sheet may contain a softener such as glycerol, ethanol formamide and methanol formamide. The coating solution may be applied to one or both sides of the sheet by brushing, spraying or dipping; the preferred resin for use in this solution is polyvinyl butyral; the aldehyde may be one of those listed above or may be isopropionaldehyde or isobutyraldehyde, formaldehyde may be used in the form of trioxymethylene, a mixture of aldehydes may be used; as catalyst sulphuric hydrochloric, toluene sulphuric or maleic acid is suitable; the solvent may comprise an alcohol such as methanol, ethanol, n-propanol, iso-propanol, n-butanol, iso-butanol'and mixtures thereof or mixtures of these alcohols with aromatic hydrocarbons such as benzene or toluene. The reaction and removal of solvent may be accomplished by heating the coated film to 100‹C for one minute, after which it may be washed in water or methyl acetate. Example III describes the application of a coating solution which contains glycollic acid and glycerol to a polyvinyl alcohol film prepared without a softener. The coating compositions described may be used as laminating adhesive for two sheets of polyvinyl alcohol film. U.S.A. Specifications 2,035,939 and 2,036,092 are referred to.

Abstract: Insulin preparations are obtained from acid alcohol-containing pancreas dispersions by preparing a clear to slightly opalescent extract by removing the dispersed constituents by centrifuging, reducing the alcohol content to a value at which the reducing material dissolves in the extract, after adjustment of the pH to a value of about 4-5.5, becomes substantially insoluble and only a very slight adsorption of insulin at the precipitated material occurs, which material is removed, and increasing the pH value of the liquid, preferably to a value of 7-8.5, in order to precipitate the non-fatty waste materials.  The alcohol content of the clear to opalescent acid containing pancreas extract may be reduced by distillation under reduced pressure.  Specification 566,351, [Group VI], is referred to.
