Degradation of PBS Introducing Crosslink by Glycerol

Article Preview

Abstract:

A series of poly (butylenes succinate) with low Glycerol (GL) fraction ranging from 0 to 6‰ were synthesized by two step melting condensation. By this method, some three-dimentional branch or crosslink structure was introduced to the linear aliphatic chain of PBS. The sequence distribution, GL fraction, crystal structure and degradability were investigated. The degrability of PBS enhanced when GL was led into polymer chain as the crystalline (χc) decreased with GL increasing. And the degradation first happened in amorphous region and then crystal region.
