PURPOSE: A manufacturing method of a crosslinked aromatic polyester is provided to improve thermal resistance, thermal stability, and mechanical properties of a crosslinked aromatic polyester by crosslinking a photo initiator-containing aromatic polyester. CONSTITUTION: A manufacturing method of a crosslinked aromatic polyester comprises a step of manufacturing an aromatic polyester which contains a photo initiator, by mixing 5-14 weight% of the photoinitiator and aromatic polyester and melting, compressing, and cooling the mixture; a step of sublimating the aromatic polyester at 190-210°C for 5-10 minutes which contains the photoinitiator; and a step of radiating aromatic polyester with a amount of 150-250 J/cm^2 to manufacture a crosslinked polyester. |
