| Abstract: | In this paper,the results obtained from the differential scanning calorimetric method (DSC method) for melting point determination of slice of bottle-grade polyester under different conditions are compared with those obtained by using the melting-point microscopic method.The findings of DSC method are significantly different conditions.It is concluded that DSC method must not be replaced by the latter.This research provides a basis for selection of methods and testing conditions in melting point determination of slice of bottle-grade polyester. |
