Abstract
Dual cure site acrylate elastomers containing both active halogen and carboxyl groups are compounded with a combination of 2,5-dimercapto-1,3,4-thiadiazole, a Group IVA metal oxide or salt thereof and a tetraalkyl thiuram sulfide to provide compounds having an excellent scorch/cure rate balance and balance of desirable physical properties in the vulcanizates thereof.
