Abstract

In order to know the change of weight loss, crystallinity, crystallite size(010) plane, and thermal properties of PET films which had before drawn and annealed at various temperature. It were treated in sodium triethylene glycolate-triethylene glycol(STEG-TEG) were prepared. The following results were abtain. The weight loss of PET films were increasing with increaing treated time in STEG-TEG solution and It showed a linear rlationship to the treated time. The crystallinity and crystallite size(010) plane of PET films decreased with increasing decomposition ratio when PET films were treated with before annealed under 16$0^{\circ}C$. The crystalline region on the surface of samples were decompose to thermal unstable crystalline structure
