  • Peroxides, their preparation process and use
    Patent number: 6770774
    Abstract: 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
    Patent number: 6482970
    Abstract: The invention is drawn to compounds of formula (I) which is HOO—C(R1)(R2)—OO—(R1)(R2)—OO—(C═O)—(O)nR3 wherein n is 0 or 1, R1 and R2 are independently selected from the group consisting of H, C1-C20 alkyl, C3-C20 cycloalkyl, C6-C20 aryl, C7-C20 aralkyl, C7-C20 alkaryl which may be optionally substituted or R1 and R2 can form a C3-C12 cycloalkyl group and R3 is selected from C1-C20 alkyl, C3-C20 cycloalkyl, C6-C20 aryl, C7-C20 aralkyl, and C7-C20 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.
