Example Embodiment
[0043] Example 1
[0044] Add bishydroxyethyl terephthalate into the esterification reaction layer, keep the temperature at 250°C and the pressure at 1.2×10 5 Pa, 10 parts by weight of TPA (terephthalic acid) and 4.5 parts by weight of EG (ethylene glycol) slurry were gradually added to the esterification reaction layer within 4 hours, and then the esterification reaction was carried out for 1 hour. Finally, 12.3 parts by weight were taken from the obtained esterification reaction product and added to the polycondensation reaction layer.
[0045] Keep the esterification reaction product at 250°C under normal pressure, add a defoamer (methyl silicone oil) equivalent to 0.01% of the polyester weight and phosphoric acid equivalent to 18ppm of the polyester weight in terms of phosphorus atoms, and stir for 5 minutes Add antimony trioxide equivalent to 230ppm of polyester weight in terms of antimony atoms, cobalt acetate equivalent to 15ppm of polyester weight in terms of cobalt a...
Example Embodiment
[0046] Example 2
[0047] Add the Y-10000 (structure shown in formula 4 that is equivalent to polyester weight 5wt%) in the polycondensation reaction, R 1 Be ethylene, molecular weight 10000g / mol), other are with embodiment 1.
Example Embodiment
[0048] Example 3
[0049] In the polycondensation reaction, Y-4000 equivalent to 15 wt% of the polyester weight was added, and the others were the same as in Example 1.
