Novel functionalized peroxides which may be used as crosslinking, grafting and curing agents, initiators for polymerization reactions and as monomers for condensation polymerizations to form peroxy-containing polymers, which in turn can be used to prepare block and graft copolymers, have the following Formula I: ##STR1## R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, X, Y.sup.1, Y.sup.2, Y.sup.3, Z.sup.1, Z.sup.2, x, y and z are as defined in the Summary of the Invention. The compounds of Formula I may be prepared by reacting hydroxy-containing tertiary hydroperoxides with diacid halides, phosgene, dichloroformates, diisocyanates, anhydrides and lactones to form the functionalized peroxides. These reaction products may be further reacted, if desired, with dialcohols, diamines, aminoalcohols, epoxides, epoxy alcohols, epoxy amines, diacid halides, dichloroformates and diisocyanates to form additional functionalized peroxides.
A process for curing an elastomer resin, comprising heating an elastomer resin without unsaturation and about 0,001% by weight to about 10% by weight of a peroxide compound at a temperature effective to cure the elastomer resin, the peroxide compound having the following Formula I:
A process for crosslinking an olefin polymer, comprising heating a non-crosslinked olefin polymer and about 0.001% by weight to about 10% by weight of a peroxide compound at a temperature effective to crosslink the olefin polymer, the peroxide compound having the following Formula I:
A process for reducing the molecular weight of a propylene polymer and modifying the molecular weight distribution of a propylene polymer comprising heating a propylene polymer selected from the group consisting of polypropylene polymers and propylene copolymers and about 0.001% by weight to about 5% by weight of a peroxide compound at a temperature effective to reduce the molecular weight and to modify the molecular weight distribution of the propylene polymer, the peroxide compound having the following Formula I;
