Document Type and Number:
WIPO Patent Application WO/2020/026746
Kind Code:
A1
Abstract:
A method for producing a liquid-crystalline resin by reacting one or more starting-material monomers comprising at least one compound selected from the group consisting of aromatic hydroxycarboxylic acids and polymerizable derivatives thereof, the method including a step in which the starting-material monomers are condensation-polymerized in the presence of either an acidic compound having a B-O (boron-oxygen) bond or a compound capable of yielding the acidic compound in the reaction system.
