Abstrakt: The adhesion of low-density polyethylene to steel and glass changes when water and acid molecules penetrate to the polymer-substrate interface. Their removal leads to total or partial recovery of the initial adhesion. An adhesive bond between polyethylene and the substrate was observed at room temperature as well as at 50° C. The results are explained in terms of the dynamic adsorption-desorption behavior of polyethylene adhesion. It is suggested that the adhesion is based is based on the van der Waals interaction between the substrate and the polar surface groups of the polymer.
