    Abstract: Blends of meta and para isomers of .alpha., .alpha.'-bis(t-butylperoxy) diisopropylbenzene are disclosed as well as methods of producing blends of .alpha., .alpha.'-bis(t-butylperoxy) diisopropylbenzene with desired ratios of meta and para isomers.Additionally, blends of meta and para isomers of .alpha., .alpha.'-bis(t-butylperoxy) diisopropylbenzene and tertiary alkyl cumyl peroxides are disclosed.The peroxides are useful for absorbing in polymers and subsequently crosslinking the polymers. The peroxide blends may be adjusted to have melt points below temperatures at which the polymers become difficult to process during the absorption step because of stickiness.

    Abstract: A secondary carbon atom in an alkane, including alkyl groups attached to aromatic rings, or cycloalkane is oxidized by molecular oxygen to the corresponding hydroperoxide in the absence of a catalyst. The oxidation is carried out in the presence of a tertiary hydroperoxide initiator which provides the free radicals needed to maintain the reaction. The amount of tertiary alcohol in the initiator is limited.
