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.

Epoxidized polyalkenylenes and method for their preparation

An adhesion promoter additive contains at least one unsaturated, amorphous polyester containing 1) an acid component comprising at least one &agr;,&bgr;-unsaturated dicarboxylic acid, and 2) an alcohol component. The alcohol component contains at least 5% of a dicidol mixture of the isomeric compounds a) 3,8-bis(hydroxymethyl)tricyclo&lsqb;5.2.1.0 &rsqb;decane, b) 4,8-bis(hydroxy-methyl)-tricyclo&lsqb;5.2.1.0 &rsqb;decane and c) 5,8-bis-(hydroxymethyl)tricyclo&lsqb;5.2.1.0 &rsqb;decane. Each isomer is present in the dicidol mixture in a proportion of from 20 to 40% by weight. A sum of the isomeric compounds a)-c) is from 90 to 100% by weight.
