preparation example Construction
[0091] Regarding the preparation method of the polyethylene emulsion composition, first, the ethylene-unsaturated carboxylic acid copolymer is put into, for example, a homogenizer device with an aqueous medium, and heated at 70 to 250°C as necessary, in the form of an aqueous solution or the like. Appropriately add an amine with a boiling point below 100°C and a compound of a monovalent metal (add an amine with a boiling point below 100°C first, or add an amine with a boiling point below 100°C and a compound of a monovalent metal approximately at the same time), and use high shear Stir vigorously. Silica particles, a cross-linking agent, and the like may be added at any stage, but it is preferable not to apply heat so that the cross-linking reaction does not proceed and gelation occurs after the addition of the cross-linking agent.
[0092] In the above-mentioned polyethylene emulsion composition, within the range that does not hinder the purpose of the present invention, it i...
