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.
Claims13
A process for epoxidizing an ethylenically unsaturated isobutene polymer, wherein the process comprises contacting an organic phase comprising the isobutene polymer with an aqueous phase comprising formic acid and hydrogen peroxide, wherein water is removed by azeotropic distillation during the epoxidation reaction.
