The preparation method of the polybutylene succinate resin composition has the characteristics of simple and continuous process and high production efficiency, and the prepared product has stable quality.

Description

technical field [0001] The present invention relates to the field of modification of polymer materials, in particular to a polybutylene succinate resin composition and a preparation method thereof and products comprising the polybutylene succinate resin composition, especially a polybutylene succinate resin composition A high-strength and toughened polybutylene succinate resin composition, a preparation method thereof, and products comprising the polybutylene succinate resin composition. Background technique [0002] Polybutylene succinate (PBS) is a new type of material with good mechanical properties, degradation properties and processing properties. It has a wide range of applications in the fields of material packaging, agriculture and biomedical polymers. prospect. However, pure PBS has highly hydrophobic and flexible molecular chains, and its shortcomings of high crystallinity, poor toughness and low strength limit its application in many fields. Therefore, in order ...
