| 中文摘要 | the toughness of polypropylene (pp)/ethylene-propylene-diene monomer (epdm) blends was studied over wide ranges of epdm content and temperature. in order to study the effect of notch radius (r), the toughness of the samples with different notch radii was determined from izod impact test. the results showed that both toughness and brittle-ductile transition (bdt) of the blends were a function of r, respectively. at test temperatures, the toughness tended to decrease with increasing 1/r for various pp/epdm blends. moreover, the brittle-ductile transition temperature (t-bt) increased with increasing 1/r, whereas the critical interparticle distance (idc) reduced with increasing 1/r. finally, it was found that the different curves of idc versus test temperature (t) for different notches reduced down to a master curve if plotting idc versus t-bt(m)-t, where t-bt(m) was the t-bt of pp itself for a given notch, indicating that t-bt(m)-t was a more universal parameter that determined the bdt of polymers. this conclusion was well in agreement with the theoretical prediction. |
