原始语种摘要: Abstract(#br)Blends of the zinc salt of poly(ethylene- co -methacrylic acid) (ZnEMA) and the zinc salt of sulfonated ethylene-propylene-diene monomer rubber (SEPDM), show thermoplastic elastomeric behaviour. The physical properties of the blends are greater than that predicted by the additivity rule. Results of dynamic mechanical analyses show ionic transitions in addition to T g in the case of neat polymers and blends. Dielectric thermal analyses show that the activation energy due to ionic groups in dipolar relaxation is highest in the case of the 50/50 ZnEMA/SEPDM blend, presumably due to formation of interfacial ionic aggregates in the blend, evidence of which was obtained by infra-red spectroscopic studies. Reprocessability studies in the Monsanto processability tester show that the...
