Use of a unsaturated diacyl or acylcarbonate peroxides in cross-linking processes

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...

Beschreibung
Zusammenfassung:	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.
