| 中文摘要 | poly(propylene carbonate) (ppc) showed predominantly degradation under electron-beam irradiation, accompanied by deterioration of its mechanical performance due to sharp decrease of the molecular weight. crosslinked ppc was prepared by addition of polyfunctional monomer (pfm) to enhance the mechanical performance of ppc. when 8 wt% of pfm like triallyl isocyanurate (tail) was added, crosslinked ppc with a gel fraction of 60.7% was prepared at 50 kgy irradiation dose, which showed a tensile strength at 20 degrees c of 45.5 mpa, whereas it was only 38.5 mpa for pure ppc. the onset degradation temperature (t-i) and glass transition temperature (t-g) of this crosslinked ppc was 246 degrees c and 45 degrees c, respectively, a significant increase related to pure ppc of 211 degrees c and 36 c. therefore, thermal and mechanical performances of ppc could be improved via electron-beam irradiation in the presence of suitable pfm. |
