  The invention relates to curing process wherein specific unsaturated diacyl-peroxides and/or unsaturated acylperoxycarbonates are used. These peroxides were found to be pre-eminently suited to the curing of silicone rubbers and polyester resins. Their use does not lead to blooming, bad smell and/or discoloration of the cured product, while allowing low residual monomer levels to be obtained at processing temperatures below the temperature used in conventional processes wherein peroxyesters are used.

  本发明涉及使用特定不饱和二酰过氧化物和/或不饱和酰过氧碳酸盐的固化工艺。研究发现，这些过氧化物特别适用于硅橡胶和聚酯树脂的固化。使用这些过氧化物不会导致固化产品开花、产生异味和/或变色，同时可以在低于使用过氧化酯的传统工艺温度下获得较低的残留单体含量。

  UV-visible absorption spectra and kinetic data obtained at room temperature are reported for three (alkenylcarbonyl)oxyls: trans-(CH3)3CCH = CHC(O)O., 1a; trans-C6H5CH = CHC(O)O., 1b; (CH3)2C = CHC(O)O., 1c; and two (alkynylcarbonyl)oxyls: (CH3)3CC = CC(O)O., 2a; C6H5C = CC(O)O., 2b. Rate constants for decarboxylation of 1a, 1b, 2a, and 2b are estimated to be less-than-or-equal-to 1.1 x 10(7), 1 x 10(6), 5 x 10(5) and 2 x 10(5) s-1, respectively. The first-order decay of 1c would appear to occur primarily by an intramolecular H atom abstraction, k approximately (2 +/- 1) x 10(7) s-1. The (alkynylcarbonyl)oxyls are more reactive than the (alkenylcarbonyl)oxyls in a variety of H atom abstraction reactions, e.g., with c-C6H12, and addition reactions, e.g., with C6H5CH = CH2. Combining the present and earlier5-7 kinetic data for carbonyloxyls yields the following order of decreasing reactivity for hydrogen abstraction and addition reactions: RC = CC(O)O. greater-than-or-equal-to ROC(O)O. > RR'C = CHC(O)O. greater-than-or-equal-to C6H5C(O)O. The reactivities of meta- and para-substituted aroyloxyls can be correlated with the intrinsic acidities and with the pK(a)'s of the corresponding benzoic acids, reactivity increasing with acid strength.
