| titleOfInvention | Method for producing liquid crystal polyester |
| abstract | Disclosed is a method for producing a liquid crystal polyester, which includes the steps of: (1) polycondensing a mixture of 70.5 to 71.5 mol% of a compound represented by the defined formula (I) (for example, 4-acetoxybenzoic acid) with 28.5 to 29.5 mol% of a compound represented by the defined formula (II) (for example, 6-acetoxy-2-naphthoic acid) to form a prepolymer, wherein the prepolymer has a flow initiation temperature of 200 DEG C or higher, and the mixture is polycondensed until reaching the temperature which is at least 30 DEG C lower than the polycondensation temperature; (2) removing the prepolymer in a molten state, followed by solidification and further grinding to produce prepolymer particles; and (3) subjecting the prepolymer particles to a heat treatment at 200 to 310 DEG C under circulation of an inert gas while remaining in a solid phase state. |
