Abstract

The effects of sulfonate group and composition of sulfonateionomer (SPSN) with low molecular mass on the morphologies, non-isothermal crystallization and melting behaviors of poly(ethylene terephthalate) (PET) in PET/SPSN blends are investigated by thermogravimetric analysis (TG). Sulfonateionomer (SPSN) is synthesized from polypropylene wax by two steps, and at 300°C the mass loss of SPSN is only 1wt % with a good thermal stability. The result shows that sulfonateionomer could is an effective nucleating agent.
