    Abstract: An isobutene polymer which has an average of at least 1.4 terminal 1,3-propanediol groups is described, as is a crosslinking product thereof. Suitable crosslinkers are difunctional or higher-functionality isocyanates or epoxy compounds having at least two epoxide groups. The crosslinking products exhibit high storage moduli even at elevated temperatures.
