The invention relates to peroxides derivable from The invention further relates to the process to make these peroxides as well as to their use in polymerization, curing, and modification reactions.

Ketone peroxide derivatives, their preparation and use

The invention relates to a preparation process for making peroxy esters and peroxy carbonates, peroxy ester peroxy carbonates, mixed diperoxides, mixed diperoxy esters, and mixed diperoxy carbonates, and to specific monoperoxy esters, monoperoxy carbonates, mixed peroxides, mixed diperoxy esters, mixed diperoxy carbonates, peroxy ester peroxy carbonates, and mixtures thereof. The process involves the reaction of a type-3 ketone peroxide with a reactive carbonyl compound and optional subsequent reaction with an alkyl vinyl ether, acetal, halogen formate, or carboxylic acid anhydride.

Peroxides, their preparation process and use

The invention is drawn to compounds of formula (I) which is HOO&mdash;C(R1)(R2)&mdash;OO&mdash;(R1)(R2)&mdash;OO&mdash;(C&boxH;O)&mdash;(O) R3 wherein n is 0 or 1, R1 and R2 are independently selected from the group consisting of H, C -C alkyl, C -C cycloalkyl, C -C aryl, C -C aralkyl, C -C alkaryl which may be optionally substituted or R1 and R2 can form a C -C cycloalkyl group and R3 is selected from C -C alkyl, C -C cycloalkyl, C -C aryl, C -C aralkyl, and C -C alkaryl which can be optionally substituted; a process for the preparation of the peroxy esters or peroxy carbonates of formula (I); and the method of using the compounds as polymer initiators or curing agents.
