| titleOfInvention | Polyamides and corresponding polymer compositions and articles |
| abstract | Described herein are polyamides (PA) derived from the polycondensation of monomers in a reaction mixture comprising: (1) a diamine component (A) comprising 20 mol% to 95 mol% of a C4 to C12 aliphatic diamine, and 5 mol% to 80 mol% of a bis(aminoalkyl)cyclohexane, where mol% is relative to the total moles of each diamine monomer in the diamine component; and a dicarboxylic acid component (B) comprising: 30 mol% to 99 mol% of terephthalic acid and 1 mol% to 70 mol% of a cyclohexane dicarboxylic acid, wherein mol% is relative to the total moles of each dicarboxylic acid monomer in the dicarboxylic acid component. It was surprisingly discovered that, with the particular combination of the bis(aminoalkyl)cyclohexane and the cyclohexanedicarboxylic acid, the polyamides (PA) had, on the whole, improved thermal performance relative to analogous polyamides, in which the cyclohexanedicarboxylic acid is replaced with an aromatic dicarboxylic acid. |
