Abstract
Amorphous polyamide compositions are provided which are transparent and have improved glass transition and thermal decomposition temperatures. The polyamide compositions of the present invention can be prepared as the polymeric condensation product of a diamine component comprising neopentyldiamine, and a diacid component comprising an aromatic dicarboxylic acid.
