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.
