The invention discloses a novel bio-based PBAT synthesis method and application thereof. In the synthesis process, by directly adding polyol in the synthesis stage, high molecular weight polybutylene adipate terephthalate (PBAT) can be synthesized, and It can realize the controllable synthesis of molecular weight, with uniform molecular weight and uniform molecular chain structure; in addition, the added polyol, the raw material is easy to obtain, the addition amount is small, and the product performance will not be affected; finally, through the control of the process and the reaction additives The optimization of the method greatly shortens the reaction time, the synthesized product has good color and luster, and has good mechanical properties, complete biodegradation, and can be widely used in the fields of consumer goods such as packaging materials and disposable tableware. |
