Abstract
Curing reactions of ethylene methyl acrylate (EMA) polydimethyl siloxa ne (PDMS) rubber blends have been investigated by differential scannin g calorimetry (DSC) and by Rheometry. The curing exoterms obtained fro m DSC curves have been analysed to derive the kinetic parameters assoc iated with the curing process. Crosslinking of EMA-PDMS rubber blends follow first order kinetics. The effect of blend ratio and peroxide co ncentration on the crosslinking characteristics of the blends have als o been investigated.
