Document Type and Number:
WIPO Patent Application WO/2023/039923
Kind Code:
A1
Abstract:
A semi-aromatic polyester, and a preparation method therefor and an application thereof. In the present invention, on the basis of the total molar amount of diacid, the molar content of a repeating unit -CH2 CH2CH2CH2-O- in dimerization (1,4-butanediol) is controlled to be 0.05-0.35 mol%, which can effectively improve the resin color of the semi-aromatic polyester.
