A description is given of a semi-interpenetrating network having a first phase of a linear noncrosslinked isobutene polymer and a second phase of a crosslinked polymer, wherein the crosslinked polymer is obtained by crosslinking molecular enlargement reaction in the presence of the isobutene polymer. The crosslinked polymer is preferably obtained by free-radical polymerization of ethylenically unsaturated monomers comprising at least one polyethylenically unsaturated monomer. The networks are suitable as molding compounds having gas and moisture barrier effect or as adhesives.
