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.
Claims17
An article of manufacture, having adhesive properties, and comprising a plastics matrix in which is dispersed a gelatinous adhesive composition present in quantities between about 30% and 50% by weight of the dispersion, said gelatinous adhesive composition comprising the product resulting from heating together in the absence of solvent:
- (a) at least one polyhydric alcohol, and
- (b) 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, to promote chemical reaction between components (a) and (b) and to drive off water produced in the reaction, the reaction being carried substantially to completion.
