The crystallinity of hydroxyalkylformamides‐platicized thermoplastic starch (HAFTPS) was characterized by X‐ray diffraction (XRD). The HAFTPS crystallinity related to the structure of plasticizer hydroxyalkylformamides (HAF). If there was one H atom attaching to N atom of HAF, the corresponding HAFTPS only had VA crystallinity; if there was no H atom attaching to N atom of HAF, the corresponding HAFTPS had EH crystallinity due to the bulky plasticizer.
