PROCESS FOR PREPARING A FURAN-BASED POLYAMIDE, A FURAN-BASED OLIGOMER AND COMPOSITIONS AND ARTICLES COMPRISING THE FURAN-BASED POLYAMIDE |
摘要 |
A furan-based polyamide is prepared by the following steps: (1) preparing a furan-based oligomer of formula (1) H2N—R—(NH—CO—F—CO—NH—R)n—NH2 (1) where R is a hydrocarbon moiety and F is a furan (cyclo-C4H2O) moiety and n represents the average degree of oligomerization, and where n is within the range of 1 to 10 by reacting 2,5-furandicarboxylic acid or its derivative with a diamine at a temperature of at most 100° C.; (2) contacting the oligomer of step (1) with a bifunctional linker selected from an acid or a derivative thereof where the acid is furandicarboxylic acid or a non-aromatic dicarboxylic acid; provided that if the hydrocarbon moiety R is aromatic, then the bifunctional linker is an aromatic dicarboxylic acid or a derivative thereof, at a mole ratio of the oligomer to the difunctional linker within the range of 0.8 to 1.5 at polycondensation conditions, and (3) isolating the resulting polyamide. |

1. A process for preparing a furan-based polyamide, said process comprising the following steps:
(1) preparing a furan-based oligomer of formula (1)
H2N—R—(NH—CO—F—CO—NH—R)n—NH2 (1) wherein R is a hydrocarbon moiety and F is a furan (cyclo-C4H2O) moiety and n represents the average degree of oligomerization, and wherein n is within the range of 1 to 10, by reacting 2,5-furandicarboxylic acid or its derivative with a diamine at a temperature of at most 100° C.; (2) contacting the oligomer of step (1) with a bifunctional linker selected from an acid or a derivative thereof wherein the acid is furandicarboxylic acid or a non-aromatic dicarboxylic acid; provided that if the hydrocarbon moiety R is aromatic, then the bifunctional linker is an aromatic dicarboxylic acid or a derivative thereof, at a mole ratio of the oligomer to the difunctional linker within the range of about 0.8 to about 1.5 at polycondensation conditions, and (3) isolating the resulting polyamide. |
