ABSTRACT:
This invention embraces a method of controlling the impermeability of an organic polymer film to gases such as oxygen, aroma, flavor and fragrance and the like to produce gas impermeable organic polymer films by coating with a mixture of a siloxane monomer with carboxylic acid in an alcohol solvent and evaporating the solvent to complete the formation of Si--O--Si bonds; and then polymerizing and grafting the coating, preferably by electron beam radiation, to the polymer film. Improved coated polymer films and formulation products therefor are also provided.
