| Abstract: | PTT was synthesized in direct esterification process route by domestic biological 1,3-PDO and PTA as raw materials. Polycondensation process were studied,and IR were characterized for PTT. The results showed that： PTT can be synthesized in catalyst A and domestic biological 1,3-PDO. And the better polycondensation process is temperature： 255 ℃,pressure 50 Pa,time： 3. 5 ～ 4 h. |
