Abstract
A method is provided for treating ionomeric polymers so as to inhibit the tendency of the polymers to form films. A coating composition including the treated ionomeric polymer is suitable for coating glassware so as to provide glassware having improved resistance to abrasion. The ionomeric polymer coating on the glassware resists film formation when the coating is inadvertently applied to the interior surface of the glassware. The method includes the step of adding colloidal silica to an aqueous dispersion of an ionomeric polymer.
