## Abstract The technical properties and the network structure of carboxylated nitrile rubber (XNBR) having a mixed crosslink system of sulfur and metal carboxylate have been studied. XNBR of different carboxyl contents (Krynac 221, Krynac 110C), yielding different concentrations of ionic crosslink
The vulcanization of carboxylated nitrile rubber (XNBR) with zinc peroxide, which produces ionic crosslinks, has been studied in relation to vulcanization time. Vulcanized compounds present two transitions, corresponding to the glass transition of the polymer at low temperatures and the ionic transi
