Whe the loadi g of talc w as 0. 5 wt%, the crystallizatio temperature w as i creased by 11. 36 e based o eat PET . Ozaw a, Jezior y a d Mo methods w ere used to describe the o -isothermal crystallizatio ki etics. It w as fou d that Jezior y a d Mo methods could w ell describe the o - isothermal crystallizatio , w hile Ozaw a w as ot suitable. Because of the good dispersio of talc i PET , the thermal property of PET was w ell mai tai ed, a d the te sile stre gth w as improved 12 %.
