Abstract
The effect of blend ratio and the compatibilization/curing process on the thermal ageing of natural rubber (NR)/ethylene-vinyl acetate copol ymer (EVA) blends have been investigated. Poly(ethylene-co-vinyl alcoh ol-co-vinyl mercaptoacetate) (EVASH) was employed as compatibilizing a gent and dicumyl peroxide (DCP) as curing agent. The resistance to the rmal ageing is better for those blends containing EVASH. The efficienc y of EVASH as a stabilizer for rubber degradation is also indicated by thermogravimetric analysis and by the determination of the molecular weight of the rubber phase after processing and ageing.
