Title:
POLYESTER, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/040768
Kind Code:
A1
Abstract:
Disclosed in the present invention are a polyester, and a preparation method therefor and an application thereof. The polyester comprises repeating units derived from the following components: a first component A, based on the total molar weight of the first component A, comprising: a1) 81-100 mol% succinic acid or an ester derivative or anhydride derivative thereof, and a2) 0-19 mol% of a dicarboxylic acid other than succinic acid, or an ester derivative or anhydride derivative thereof; a second component B: 1,4-butanediol; and a third component C: a dimer(1,4-butanediol), based on the total molar weight of the first component A, the molar content of repeating unit-CH2CH2CH2CH2-O- in the third component C is 0.05-3.0 mol%. In the present invention, the molar content of repeating unit-CH2CH2CH2CH2-O- in dimer(1,4-butanediol) is controlled to 0.05-3.0 mol%, and thus, the resin color of the polyester can be effectively improved.
