Aqueous dispersions of vinylidene chloride resins |
摘要 |
An aqueous dispersion of vinylidene chloride resin which, when coated onto a synthetic resinous film substrate, has the combined properties of: (1) good adhesion to the substrate; (2) good adhesion of a printing ink to the coating; (3) satisfactory barrier to gases (especially oxygen) and water vapor; and (4) a high resistance to boiling water treatment. The vinylidene chloride resin must also have polymerized therein methyl methacrylate, methacrylonitrile and methacrylic acid. A total amount of methacrylic acid must be between 1x10-4 and 3x10-4 moles of methacrylic acid per gram of polymer solids. A portion of the total amount of methacrylic acid exists in a form titratable with a 1/20 Normal aqueous solution of sodium hydroxide. The portion must be the less of (a) about 1.3x10-4 moles per gram of polymer solids or (b) about 60 percent of the total amount.
