Abstract: Linear or star block copolymers which have at least one polymer block A which is essentially composed of isobutene units and at least two polymer blocks B which are essentially composed of units which are derived from vinylaromatic monomers are used as resilient sealing material. In particular, such sealing materials are used for sealing the edge joints in insulation glass panes, and insulation glass panes have a flexible edge joint seal which contains one of the block copolymers.
