Abstract
A novel composition comprises a block copolymer of a polyetheramide, e.g., poly-(4,7-dioxadecamethylene adipamide) and a random copolymer resulting from the polymerization of an ether free polyamide precursor, e.g., hexamethylenediamine salt of adipic acid and a precursor of a polyetheramide. The block copolymer can be more easily processed into useful articles such as fiber and film because it differs structurally from a corresponding block copolymer of homopolymers of polyetheramide and polyamide.
