Abstract: A polyamide composition comprising from 45 wt % to 95 wt % of polyamide polymer and from 5 wt % to 55 wt % of a modifier comprising a C18-44 dimer acid or a C18-44 dimer amine or a combination thereof. A number average molecular weight of the polyamide polymer is less than 30,000 g/mol. The polyamide composition has a chemical resistance, as measured by exposure to HCl (10%) for 14 days at 58° C., resulting in a weight loss of less than 3.0 wt %; and a moisture uptake of less than about 2.0 wt % moisture at 95% RH. A process for preparing the polyamide composition is also disclosed.
