ABSTRACT:
Curable perfluoroelastomer compositions are prepared in the presence of an initiator system comprising a mixture of a persulfate salt and a reducing agent wherein the amount of reducing agent present is no more than 20 mole percent of the total initiator system. The perfluoroelastomer is isolated and decarboxylated, thereby providing a product having excellent processability.
