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

Vulcanization of carboxylated nitrile rubber (XNBR) with a mixed system based on zinc peroxide and sulphur accelerators produces materials with favourable mechanical properties because of the formation of ionic aggregates which give the vulcanized compounds a certain rigidity. These properties are d
## Abstract Zinc neutralized maleated natural rubbers (ZnβMNR) were prepared by solution grafting and neutralization with zinc acetate in oneβstep. It was later used for blending with carboxylated nitrile rubber (XNBR) in the composition of 50/50 parts by weight. The effect of grafted anhydride con
