ABSTRACT:
The present invention provides a method for the suppression of bloom in polymeric articles that are crosslinked using α,α′-bis(tert-butylperoxy) diisopropylbenzene, polymeric compositions comprising α,α′-bis(tert-butylperoxy) diisopropylbenzene that are non-blooming, agents for crosslinking polymers, and crosslinked polymeric articles formed in accordance with the method of the invention. Agents for crosslinking a polymeric composition according to the invention include a mixture of α,α′-bis(tert-butylperoxy) diisopropylbenzene and a nonionic compound having a hydrophobic group bonded to a polyethylene glycol chain via an ether linkage, wherein the hydrophobic group includes about 12 or more carbon atoms at least 8 of which are in the form of an alkyl chain, and wherein the polyethylene glycol chain includes about 20 or more ethylene oxide units.
