WebCrystallinity The crystallinity of a polymer refers to the degree as to which there are regions where the polymer chains are aligned with one another. However, in order for this to occur, some degree of stereoregularity is required. This is because the crystalline regions are formed from the stereoregular blocks in the polymer chain. WebNov 7, 2024 · Crystallinity analyses by differential scanning calorimetry (DSC): The crystallinity of untreated and NaOH pretreated PET was measured by DSC (METTLER TOLEDO DSC2). Scans were equilibrated at 0 °C for 1 min, heated to 300 °C at a heating rate of 10 °C⋅min −1 and maintained at 300 °C for 1 min, then the sample was cooled to …
