20220289909, Sep 15, 2022

Filed:

Aug 25, 2020

Appl. No.:

17/635784

Inventors:

- Alpharetta GA, US
Joel FLORES - Alpharetta GA, US

International Classification:

C08G 69/36
C08K 7/14
C08J 5/04

Abstract:

Described herein are polyamides (PA) incorporating a cycloaliphatic monomer containing a cyclohexyl group. It was surprisingly discovered that by incorporating the cycloaliphatic monomer containing a cyclohexyl group, the resulting polyamides (PA) had significantly reduced water absorption and significantly increased Tg, while maintaining high Tm, Tc and good mechanical properties, relative to analogous polyamides free of the cycloaliphatic monomer and PA6,T based polyamides copolymerized with either or both of isophthalic acid and adipic acid.

International Classification:

C08G 69/26

Abstract:

The present invention relates to copolyamides comprising 4-(aminomethyl)benzoic acid (4-AMBa). The present invention also relates to polymer compositions comprising such copolyamides, as well as articles comprising the same and methods of using said articles to prepare windows, clear containers for cosmetic products packaging or glass frames & lenses. The present invention also relates to the use of the copolyamide, as such or in a composition of matter, for the manufacture of three-dimensional objects using an additive manufacturing system, for example an extrusion-based manufacturing system.

C08G 69/28

Abstract:

Polyamides are made from the polycondensation of monomers including from 15 to 80 mol % of 2,5-furandicarboxylic acid (FDCA), from 20 to 85 mol % of at least one aromatic dicarboxylic acid and from 50 to 100 mol % of at least one aliphatic diamine selected from those including 6 and 7 carbon atoms. A process allowing the synthesis of high molecular weight polyamides made from the above mentioned monomers is also described. Finally, compositions and articles including the same polyamides are also disclosed.
