- PCT resin was prepared in the same manner as in Example 4, except that 400 g of 1,4-cyclohexanedimethanol 2.0 kg in Example 4 was replaced with 260 g of ethylene glycol. Comparative Example 1
- PCT resin was prepared in the same manner as in Example 1, except that antimony trioxide was not used in Example 1. Comparative Example 2
- PCT resin was prepared in the same manner as in Example 1, except that 300 g in 2.0 kg of 1,4-cyclonucleodimethanol was replaced with 280 g of ethylene glycol. Comparative Example 3
- PCT resin was prepared in the same manner as in Example 1, except that the content of antimony trioxide in Example 1 was changed to 0.02 g. Test Example
- Intrinsic viscosity measurement After dissolving PCT resin in a concentration of 1.2 g / dl in o-chlorophen was measured intrinsic viscosity at 35 ° C using a Ubbelodhe viscous tube.
- the crystallization temperature was determined in consideration of the temperature crystallization temperature of the sample, crystallization of the sample at a temperature of 240 ° C in Examples 1 to 5, crystallization of the sample at a temperature of 225 ° C in Example 6 In the case of Comparative Examples 1 and 3, the sample was crystallized at a temperature of 23 CTC, and in the case of Comparative Example 2, the sample was crystallized at a temperature of 200 ° C.
- (a) Represents the mole percent of all di-diol contained in the PCT resin by the residue of cyclonucleodimethanol (CHDM).
- CHDM cyclonucleodimethanol
- Example 6 CHDM 1600 g (11.1 mol) and 260 g (4.2 mol) of ethylene glycol (EG) were administered to the reactor, but a part of the EG was blown during reaction and the CHDM was added to the PCT resin prepared in Example 6. It was confirmed that the residues contained were 92 mol%.
