Provided is a polyether polyamide composition including 100 parts by mass of a polyether polyamide in which a diamine constituent unit thereof is derived from a specified polyether diamine compound and a xylylenediamine, and a dicarboxylic acid constituent unit thereof is derived from an &#x3b1;,&#x3c9;-linear aliphatic dicarboxylic acid having from 4 to 20 carbon atoms, having blended therein from 0.01 to 15 parts by mass of at least one molecular chain extender selected from a carbodiimide compound and a compound containing two or more epoxy groups in a molecule thereof.

Polyether polyamide composition

Provided is a polyether polyamide elastomer not only having excellent melt moldability, crystallinity and flexibility but having heat resistance. The polyether polyamide elastomer includes a diamine constituent unit derived from a polyether diamine compound (A-1) and a xylylenediamine (A-2) and a dicarboxylic acid constituent unit derived from an &#x3b1;,&#x3c9;-linear aliphatic dicarboxylic acid having a carbon number of from 4 to 20.
