Method for producing an oxidation-treated polymer solution and a method for producing a laminate using the solution

摘要

A saponified ethylene-vinyl acetate copolymer is oxidation- treated in solution in a solvent mixture of water and alcohol in the presence of hydrogen peroxide and a polyvalent metal salt to provide an oxidation- treated polymer solution. This oxidation-treated polymer solution is coated on a substrate, e.g. a polymer film, to provide a laminate.
