Process for the preparation of the composition of trioxepano and use thereof in polymers of cross-linking.The present invention relates to a process for preparing a compound of the following formula (1) trioxepano comprising less than 3.5% by weight of dialquila peroxide based on the total amount of peroxides.The said process comprising the steps of reacting a compound of the formula R ^ 3 ^ glycol Choh - CH ~ 2 ~ - C (CH ~ 3 ~) ~ 2 ~ 10 with hydrogen peroxide in the presence of an acid to form a hydroperoxide of glycol, purified hydroperoxide react the glycol from glycol, purified with A ketone or aldehyde of the formula R ^ 1 ^ R ^ 2 ^ C0 in the presence of an acid to form the compound of trioxepano,And purify the compound of trioxepano, in which ru00b9, R u00b2 and ru00b3 are independently selected from hydrogen and a group of hidrocarbila replaced or not replaced, with the condition that ru00b9 and R u00b2 are both methyl groups, R3 is not hydrogen.The priming compositions comprising the thus prepared composed of trioxepano are characterized by a processing temperature hold high in combination with a good efficiency of cross-linking.
