    Abstract: Methods and compositions for controlling polymer crosslinking are provided. The crosslinking composition includes a crosslinkable polymer, a free radical initiator, and an amine. The amine is an alkoxyaminc or a hydroxylamine. The crosslinking composition is heated to a processing temperature. The amine undergoes a cleavage reaction at or below the processor temperature to produce nitroxyl radicals in situ . The tree radical initiator forms polymer radicals at the processing temperature. The nitroxyl radicals formed in situ cap the polymer radicals to control crosslinking.
