| abstract |
The present invention relates to low viscosity and transparent polyamides and methods for their preparation. The transparent polyamines include the reaction products of fully hydrogenated dimer acid, second linear saturated dicarboxylic acid, alkylenediamine, dihexahydropyridine, and optionally different from the alkyl group. A second diamine of the amine and an optional additive. These polyamides have low melt viscosity and high light transmittance. |
