Bio-based PBS butylene succinate for Drug sustained release

Polybutylene succinate (PBS) is a kind of polymer compound with the simple structure H-[O(CH2)4OOC(CH2)2CO]n-OH. It is a white semi-crystalline polymer. Soluble in chloroform, slightly soluble in tetrahydrofuran, almost insoluble in water, methanol or ethanol. According to the different molecular structure and molecular weight, the crystallinity range is 30%~60%, and the crystallization temperature is 75℃. Its structural unit contains easily hydrolyzed ester groups, in compost and other contact with specific microorganisms and other conditions, easy to be a variety of microorganisms in nature or animals, plants in the enzyme decomposition, metabolism, and ultimately the formation of CO2 and H2O, and avoid pollution of the environment, among which, the chemical structure of the molecule, molecular weight size, morphological distribution, melting point, crystallinity on the degradation process have different effects. Polybutylene succinate (PBS) can be used as garbage bags,…
