Abstract
Sulfur free, crosslinking, scorch-retarding compositions for compounding and cure of polymers susceptible to cure by free radical initiators are disclosed.
Claims5
A sulfur free 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.
