| Abstract: | The equilibrium melting temperature (T°m) of isotactic polypropylene (iPP) was studied by DSC technique for samples with different nucleating agents including calcium carbonate(CA), terephthalic acid(DB) and glutaric acid(WA). The (T°m) values of α modification iPP crystals obtained for samples with different nucleating agents were found to be within a narrow temperature range of 488～492K, almost independent on the nucleating agents. |
