液晶聚酯的制备方法
摘要：
本发明公开了一种制备液晶聚酯的方法，其包括以下步骤：（1）在聚合罐中熔融缩聚作为单体的化合物从而生成预聚物；（2）在熔融状态下将该预聚物从聚合罐中排出，通过冷却将该预聚物固化从而制造厚度为1.6～2mm的部分占80％质量以上（整个片材为100％质量）的片材；（3）粉碎该片材；并且（4）通过加热使该粉碎品进行固相聚合。
摘要（英）：

Disclosed is a method for producing a liquid crystal polyester, which includes the following steps of: (1) melt-polycondensing a compound as a monomer in a polymerization tank to produce a prepolymer; (2) discharging the prepolymer from the polymerization tank in a molten state, and solidifying the prepolymer through cooling to produce a sheet in which a portion having a thickness of 1.6 to 2 mm accounts for 80% by mass or more (of 100% by mass of the entire sheet); (3) crushing the sheet; and (4) subjecting the crushed product to solid-phase polymerization through heating.
