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.
