Abstract
This invention pertains to scorch retardant systems for peroxide curable elastomers. Polyunsaturated monomers copolymerizable with the elastomer in the presence of peroxides are mixed with hydroquinone and sulfenamides and incorporated into elastomer formulations. The formulations are milled and cured. Excellent Mooney scorch times and hardness values, as well as other physical properties are obtained.
