FIELD: chemistry.

SUBSTANCE: object of the invention is an initiator composition containing at least two trimeric cyclic ketone peroxides: trimeric cyclic methyl ethyl ketone peroxide (3MEK-cp) of formula (I) and at least one peroxide satisfying formula (II) in which R¹–R³ represent alkyl, where these groups have from 2 to 5 carbon atoms, the total number of carbon atoms in R¹+R²+R³ is in the range of 7–15, and the molar ratio of 3MEK-cp and the total amount of peroxides satisfying formula (II) is in the range from 10:90 to 80:20. Invention also relates to a process for the preparation of this composition.

(I) (II).

EFFECT: improving the safety and stability of the composition during storage.
