| titleOfInvention | Polycyclohexane dimethylene terephthalate |
| abstract | PROBLEM TO BE SOLVED: To provide a polycyclohexane dimethylene terephthalate having good thermal stability, hydrolysis resistance and color tone and a high solid-state polymerization rate, and a high-grade polycyclohexane dimethylene terephthalate obtained by solid-phase polymerization thereof. A manufacturing method is provided. SOLUTION: Polycyclohexane dimethylene terephthalate (PCHT) having at least the characteristics of (A), (B), C) and (D), and a high-quality PC for solid-phase polymerization of the PCHT HT manufacturing method. (A) Ti in a specific state defined from the spectrum of X-ray absorption near-edge structure (XANES) of X-ray absorption fine structure analysis (XAFS) of PCHT, that is, a specific state in which arrangement with atoms existing near Ti is specified. (B) terminal C OOH groups are less than 30 eq / ton, and (C) intrinsic viscosity is IV ≧ 0.6. (D) (η) a / (η) b > 60% [(η) a : solution viscosity after standing at 300 ° C. for 1 hour, (η) b Is the solution viscosity before standing] |
