原始语种摘要: Abstract(#br)Zinc sulfonated ethylene—propylene—diene terpolymer (EPDM) behaves as an ionic thermoplastic elastomer. Both paraffin oil and dimethyl sulfoxide (DMSO) act as plasticizers for this polymer; while paraffin oil plasticizes the hydrocarbon backbone, DMSO plasticizes the ionic domains. Results obtained from dynamic mechanical analysis (d.m.a.) show that DMSO does not affect the glass—rubber transition temperature ( T g ), occurring at around −26°C, but adversely affects the broad transition in the temperature range from +27 to +80°C, which is believed to be due to the hard phase resulting from the ionic aggregates in the polymer. Paraffin oil, however, causes a lowering of the T g (from −26 to −34°C) without affecting the high-temperature transition. Results obtained from...
