Claims13
An organic peroxide formulation comprising:
- at least one organic peroxide;
- and
- at least one unsaturated scorch retarder having the structure of general formula (I):
- wherein,
- R1 is OH, O—R5, or a saturated or unsaturated, linear, branched, or cyclic C1 to C8 alkyl group;
- R2 is on each occurrence independently H or a saturated or unsaturated, linear or branched C1 to C8 alkyl group;
- R3 is on each occurrence independently H, O—R6, or a saturated or unsaturated, linear or branched C1 to C8 alkyl group;
- R4 is on each occurrence independently OH, O—R6, or a saturated or unsaturated, linear or branched C1 to C8 alkyl group;
- R5 is a saturated or unsaturated, linear or branched C1 to C8 alkyl group or —[CH2]n—OCOCR4CR2R3;
- R6 is on each occurrence independently a saturated or unsaturated, linear or branched C1 to C8 alkyl group;
- and
- n is from 2-8,
- with the proviso that one but not both of R2 and R3 are H,
- or wherein
- R1 and R2 are joined to form a 5, 6, or 7 membered ring, said ring being formed of atoms selected from C, O, and S and comprising one or two carbon-carbon double bonds and one or two carbonyl groups, said ring being optionally substituted with one or more saturated or unsaturated, linear or branched C1 to C8 alkyl group;
- R3 is H;
- or wherein
- R3 and R4 are joined to form a 5, 6, or 7 membered ring, said ring being formed of atoms selected from C, O, and S and comprising one or two carbon-carbon double bonds, said ring optionally substituted with one or more saturated or unsaturated, linear or branched C1 to C8 alkyl group;
- and
- R2 is H.

- R3 and R4 are joined to form a 5, 6, or 7 membered ring, said ring being formed of atoms selected from C, O, and S and comprising one or two carbon-carbon double bonds, said ring optionally substituted with one or more saturated or unsaturated, linear or branched C1 to C8 alkyl group;
- R2 is H;
- and
- R1, R5, R6 and n are as described above.
