Effect of glycidyl methacrylateas compatibilizeron physico-chemical properties of gamma irradiated composites ofethylene propylene diene monomer rubber / styrene butadiene rubber/ground tire rubber

ABSTRACTComposites of ethylene propylene diene monomer rubber (EPDM)/ styrene butadiene rubber (SBR)/ground tire rubber (GTR)(50/50/20) phr (part per hundred parts of rubber, by weight)loaded with different contents of glycidylmethacrylate (GMA) 2–6 phr. were irradiatedfrom 50 to 250 kGy. The physicochemical properties were investigated.Irradiation dose and GMA improved physicochemical properties, the optimum content of GMA is 6 phr at a low dose of irradiation. These results were confirmed by scanning electron microscopy (SEM).
