Abstract: An epoxidized polyalkenylene is prepared reacting a polyalkenylene, an aqueous solution of 15 to 90% by volume of hydrogen peroxide and a carboxylic acid having from 1 to 3 carbon atoms in the presence of a catalyst which is phosphonic acid, a derivative of phosphonic acid or a mixture thereof, without addition of an organic solvent or water, to obtain the epoxidized polyalkenylene. The epoxidized polyalkenylene has a number-average molar mass of between 500 and 50 000 g/mol and an epoxide oxygen content of between 1 and 25 percent by mass.
