POLY(ETHERAMIDE) SEGMENTED BLOCK COPOLYMERS (D#81,201-F) Abstract of the Disclosure An amine terminated random copolymer containing ethylene oxy/propylene oxy segments may be reacted with hexamethylene diamine and adipic acid monomers to make improved poly(etheramide) segmented block copolymers. Ordinarily, poly(pro- pylene glycol) diamines tend to phase separate under these conditions and polyamide- 6,6 could not be so modified. The resultant poly(etheramide) segmented block copoly- mer has improved impact performance, reduced modulus and lower glass transition as contrasted with the non-modified polyamide-6,6.
