preparation example Construction

[0031] The synthesis method of the above step (a) can use solution polycondensation method and bulk condensation polymerization method (bulk condensation polymerization). Also, in order to promote the polycondensation reaction in the above step (a), an acylated (especially acetylated) monomer may be used as the monomer in the above step (a). For this purpose, a step of acylation of the monomers may be further included before the above step (a).

[0032] For the solid-state polycondensation reaction in the above step (b), appropriate heat can be provided to the above-mentioned prepolymer, and the above-mentioned heat supply method can be a method using a heating plate, a method using hot air, or a method using a high-temperature fluid. In order to remove by-products generated when the solid-state polycondensation reaction occurs, purging with inert gas or vacuum can be performed.

[0051] (1) Preparation of fully aromatic liquid crystal polyester resin (LCP)

[0052] In a temperature-adjustable batch reactor with a capacity of 100 liters, add 24.4 kg of p-hydroxybenzoic acid, 10.8 kg of 4-4' bisphenol, 7.3 kg of terephthalic acid and 2.4 kg of isophthalic acid Diformic acid and nitrogen were injected to make the inner space of the reactor inert, and then 33 kg of acetic anhydride was further added to the reactor. Afterwards, after heating for 30 minutes, the temperature of the reactor was raised to 150° C., and under the above temperature conditions, the hydroxyl groups of the above monomers were acetylated for a total of 3 hours. Next, the acetic acid produced in the above acetylation reaction was removed, and the temperature of the reactor was raised to 330° C. after 3 hours of heating, and a wholly aromatic liquid crystal polyester prepolymer was prepared by polycondensation reaction of monomers. Moreover, when preparing the above-mentioned prepolyme...

Abstract

A wholly aromatic liquid crystal polyester resin compound and product are disclosed. The disclosed wholly aromatic liquid crystal polyester resin compound comprises a wholly aromatic liquid crystal polyester resin and an electroconductive filler.

Description

technical field [0001] The invention relates to a wholly aromatic liquid crystal polyester resin composition and products. More specifically, it relates to a wholly aromatic liquid crystal polyester resin compound having antistatic properties due to the inclusion of a conductive filler, and products containing the above resin compound. Background technique [0002] Wholly aromatic liquid crystal polyester resin has excellent heat resistance and dimensional stability, and also has excellent fluidity when melted, so it is widely used as a material for precision injection molding in various fields centering on the field of electronic parts use. In particular, since the above-mentioned wholly aromatic liquid crystal polyester resin has excellent dimensional stability and insulating properties, its use in connectors of electronic products and materials for bobbins (??) is gradually expanding. [0003] Whole aromatic liquid crystal polyester resin is a kind of thermoplastic poly...
