ABSTRACT:
Polyetherpolyamide copolymers are disclosed which comprise the product of the polycondensation of a diamine with the equivalent amount of a dicarboxylic acid and a common polyamide forming component, wherein the diamine contains a polyether block containing at least 3 ether oxygen atoms separated from each other by a carbon chain selected from the group consisting of linear carbon chains of at least 3 carbon atoms, branched carbon chains of at least 2 carbon atoms between the ether oxygen atoms and mixtures thereof and a common polyamide block which is mainly a homopolyamide. The present compositions exhibit improved flexibility and low temperature properties and may be processed by injection molding and extrusion techniques.
