Abstract
The aging period for chemically stabilized, adhesive activated polyester material can be reduced by contacting the material before it is substantially drawn or stretched with a composition containing a defined epoxide compound catalyzed with ions of at least one of potassium, cesium, rubidium or ammonium at a pH of between about 7.5 to about 13.0. The composition preferably also contains chloride, bromide or iodide ions which stabilizes the pH and/or an amine which improves adhesion to rubber.
