Title:

FURAN DIACID-BASED POLYAMIDE, PREPARATION METHOD THEREFOR, AND FURAN DIACID-BASED POLYAMIDE COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2023/045820

Kind Code:

A1

Abstract:

Disclosed in the present invention is a furan diacid-based polyamide, which is derived from the following repeating units: (A) 2,5-furandicarboxylic acid, (B) 1,4-cyclohexanedicarboxylic acid, and (C) 1,5-pentanediamine, wherein based on the total molar percentage of the diacid units, (A) accounts for 10-45 mol% of the diacid units. On one hand, by selecting a bio-based 2,5-furandicarboxylic acid, the resin is more environmentally friendly, and has the advantages of a melting point of 291-335℃ and lower water absorption (a water absorption rate lower than that of a polyamide with the same amido bond density); on the other hand, the rigidity of cyclohexane is higher than that of an aromatic ring, such that more hard carbon layers can be formed during combustion. In addition, the furan diacid-based polyamide has a relatively high amido bond density, and can generate a relatively excellent synergistic effect with a flame retardant, such that the flame retardant effect is excellent under the synergistic effect of the two.
