Process for the preparation of a peroxide, peroxide, use of a peroxide, and.The formulation "the present invention relates to a new class of peroxides and to a process for the preparation of these compounds having general formula (I): where n = 1 or 2, R ~ 1 ~ R ~ 2 ~ R ~ 4 ~.R ~ 5 ~ R ~ 6 ~ are independently selected from the group consisting of hydrogen, C ~ 1 ~ C ~ 20 ~ alkyl, C ~ 3 ~ C ~ 20 ~ cicloalquila, C ~ 6 ~ C ~ 20 ~ arila,C ~ 7 ~ C ~ 20 ~ aralquila and C ~ 7 ~ C ~ 20 ~ alcarila, or R ~ 1 ~ R ~ 2 ~ form a group C ~ 3 ~ C ~ 12 ~ cicloalquila, whose groups may include portions of linear or branched alkyl; and each of R ~ 1 ~,R ~ 2 ~ R ~ 4 ~ R ~ 5 ~ R ~ 6 ~ may optionally be replaced by one or more groups selected from hydroxy, alkyl alcu00f3xi, linear or branched arilu00f3xi, halogen, ester, carbu00f3xi,Nitrile and starch and R ~ 1 ~ R ~ 2 ~ may form a ring, and R ~ 3 ~ is independently selected from the group consisting of C ~ 1 ~ C ~ 20 ~ alkyl, C ~ 3 ~ C ~ 20 ~ cicloalquila, C ~ 6 ~ C ~ 20 ~ arila,C ~ 7 ~ C ~ 20 ~ aralquila and C ~ 7 ~ C ~ 20 ~ alcarila,These groups may include portions linear or branched alkyl; and R ^ 3 ^ may optionally be replaced by one or more groups selected from hydroxy, alkyl, linear or branched alcu00f3xi,Arilu00f3xi, halogen, nitrile, ester, carbu00f3xi, starch and any pair of R ~ 3 ~ R ~ 4 ~ R ~ 5 ~ R ~ 6 ~ optionally substituted may form a ring.Comprising the reaction of the corresponding ketone peroxide with general formula (II): in which n, R ~ 1 ~ R ~ 2 ~ have the significance identified.With an alkyl vinyl ether with general formula (IIIA) or with an acetal with general formula (IIIB) in R ~ 3 ~ R ~ 4 ~ R ~ 5 ~ 6 ~ ~ and R have the meaning as identified in the presence of a catalyst.The use of these peroxides as initiators of polymerization, curing unsaturated polyester, and / or modifying agent, and formulations comprising these compounds and a carrier or diluent.
