Title:
METHOD FOR PRODUCING THERMOTROPIC LIQUID CRYSTAL POLYESTER
Document Type and Number:
Japanese Patent JP2013227411
Kind Code:
A
Abstract:
To provide a method for producing a thermotropic liquid crystal polyester which enables the production efficiency of the thermotropic liquid crystal polyester to be enhanced.
A method for producing a thermotropic liquid crystal polyester is characterized in that a low polymerization degree thermotropic liquid crystal polyester powder having a melting point of 240-330°C obtained by discharge in a molten state from a reaction vessel, solidification by cooling, and comminution is fluidized in a vibrated reactor in at least the vertical direction and subjected to solid phase polymerization.
