Abstract
—The interfacial chemistry of a model poly(vinyl chloride) adhesive formulation applied to cold-rolled and galvanized steels has been studied by X-ray photoelectron spectroscopy (XPS). Chemical changes suggesting enhanced dehydrochlorination of poly(vinyl chloride) in the polymer/ metal interfacial region were observed on both substrates. An ionic chloride species (probably zinc chloride) and an increased level of hydrocarbon were observed at the adhesive/substrate interface on galvanized steel; the total amount of chlorine present near the interface was much less than in the bulk of the adhesive. On cold-rolled steel, the amount of chloride was only slightly lower near the metal surface, and no ionic chloride was observed. Polymer degradation is suggested by an increase in hydrocarbon observed at the interface. Changes in the oxidation state of the iron surface oxide were also observed.
