Claims
- 1. A crosslinking, scorch retarding mixture for crosslinking polymers capable of being crosslinked by free radical initiators and providing reduced scorch during compounding consisting essentially of:
a). at least one free radical initiator suitable for crosslinking polymers selected from the group consisting of organic peroxides and azo initiators; b). at least one hydroquinone mono alkyl or mono aryl ether; and c). at least one crosslinkage promoter.
- 2. A crosslinking, scorch retarding mixture as defined in claim 1 wherein the hydroquinone mono alkyl ether is hydroquinone monomethyl ether.
- 3. A crosslinking, scorch retarding mixture as defined in claim 1 consisting essentially of
a). 2,5-dimethyl-2,5-di(t-butylperoxy) hexane; b). di(t-butyl peroxy) diisopropyl benzene; c). triallyl isocyanurate; d). hydroquinone monomethyl ether; and e). mono-t-butyl hydroquinone.
- 4. A crosslinking, scorch retarding mixture as defined in claim 1 consisting essentially of
a). di(t-butyl peroxy) diisopropyl benzene; b). triallyl isocyanurate; and c). hydroquinone monomethyl ether
- 5. A crosslinking, scorch retarding mixture as defined in claim 1 wherein the organic peroxides are selected from the group consisting of
a). dicumyl peroxide; b). dicumyl peroxide and isopropylcumyl cumyl peroxide; and c). t-butyl cumyl peroxide.
