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.

Abstract: A process is described for epoxidizing an ethylenically unsaturated isobutene polymer, in which an organic phase comprising the isobutene polymer is contacted with an aqueous phase which comprises formic acid and hydrogen peroxide. The process affords essentially quantitative conversions after a short reaction time.
