采用MDSC对初始结晶度进行表征
|
| Manufacturers of crystalline and semi-crystalline polymers need to have a method for quickly determining the percent crystallinity of their polymers after processing. Differential scanning calorimetry (DSC) has been widely used for this purpose based on quantifying the heat of melting. (1) However, it has long been recognized that DSC only measures the sum of all thermal events occurring in the polymer during heating. Hence, if overlapping transitions such as crystallization and melting are occurring, these individual transitions may not be seen and accurately assessed. |
