Crystallinity analysis

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.
