dithiodiacetic acid and ethylene glycol were utilized to synthesize polyethylene dithiobisalate with p-toluenesulfonic acid as catalyst by melt polycondensation
introducing the disulfide bond into the polyester successfully. The influence of reaction temperature and reaction time on the molecular weight was investigated and the obtained products were characterized by GPC
TG and
1
H-NMR.
