Preparation and Characterization of Semi-aromatic Polyester Amide by One-pot Method
In order to develop highly hygroscopic modified polyester fibers, 6-amino-1-hexanol and terephthalic acid (PTA) were used as monomers, and titanium tetra-n-butoxide was used as a melt polymerization catalyst. The high molecular weight semi-aromatic polyester amides P6T6T and P6T were synthesized by a two-step feeding one-pot method and a one-step feeding one-pot method, respectively. The chemical structures, thermal properties, crystallization properties and hydrophilic properties of P6T6T and P6T were evaluated. The results showed that the different feeding methods led to certain differences in the structure and properties of P6T6T and P6T. The melting points of P6T6T and P6T were 220 ℃ and 217 ℃ respectively, the glass transition temperatures were 88 ℃ and 85 ℃ respectively, the 5% weight loss thermal decomposition temperatures were 380 ℃ and 375 ℃ respectively, and the saturated water absorption rates were 2.72% and 3.49% (about 3 to 4 times that of PET) respectively. The results indicate that both P6T6T and P6T have excellent thermal and hydrophilic properties, which are not only suitable for engineering plastics, but also have the potential to be developed into highly hygroscopic fibers.
