Synthesis and Characterization of Poly(butylenes succinate) with Control Different End-Group
Abstract:
Poly (butylenes succinate) (PBS) was synthesized by using1, 4-butanediol and succinate as starting material, titanic acid ester and acetate as catalyst, and tried to improve PBS by changing end-group to carboxyl, hydroxyl and chlorine. The results of GPC showed, molecular weight of four kinds of polymer was all beyond seventy thousand; chemical structure of the polymer was measured by FTIR and nitrogen/sulfur/chlorine elementary analyzer; PBS controlled end-group had better thermal properties by DSC and TG; different end-group had influenced mechanical properties; and biodegradability experiment results showed biodegradable speed of PBS can be controlled by changing their end-group.
