    Abstract: The present invention relates to the use of linear or star-shaped block copolymers which are provided with at least one polymer block A which mainly consists of isobutene units and at least two polymer blocks B which mainly consist of units that are derived from vinyl aromatic monomers. Said block copolymers are used as elastic sealing material. The invention especially relates to the use of such sealing materials for sealing the edge joints in insulating glass panes and insulating glass panes which are provided with a flexible edge-joint sealing which contains one of the block copolymers.
