Study on the Synthesis and Properties of PET Using Hydrotalcite as Catalyst

Li Guihe  Fu Zhifeng  Cao Ding  
【摘要】:Poly(ethylene terephthalate)(PET)was synthesized by the in-situ polymerization method using layered double hydrotalcite(LDH)as the catalyst,and the thermal and flame retardation properties of PET were investigated as required.As identified by differential scanning calorimetry(DSC)and thermogravimetric(TGA)analysis,the crystallization rate and thermal degradation temperature of the as-prepared PET sample were enhanced compared with commercial PET sample.It was confirmed from the fire-resistant property study that the LDH can be used as an efficient flame-retardant besides functioning as a catalyst in the transesterification/polycondensation process for PET synthesis.
