Title:
SEMI-AROMATIC POLYETHER ESTER, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/040769
Kind Code:
A1
Abstract:
The present invention relates to a semi-aromatic polyether ester, a preparation method therefor and the use thereof. The semi-aromatic polyether ester comprises repeating units derived from the following components: a first component A, based on the total molar amount of the first component A, comprising: a1) 35-65 mol%, preferably 40-60 mol% of at least one aliphatic dicarboxylic acid or an ester derivative thereof, or an anhydride derivative thereof; and a2) 35-65 mol%, preferably 40-60 mol% of at least one aromatic dicarboxylic acid or an ester derivative thereof, or an anhydride derivative thereof; a second component B: 1,4-butanediol; and a third component C: poly(1,4-butanediol), having a molecular formula of HO-(CH2CH2CH2CH2-O)n-H, wherein n is an integer from 2 to 200, and based on the total molar amount of the first component A, the molar content of the repeating unit -CH2CH2CH2CH2-O- in the third component C is 1.5-5.5 mol%.
