ABSTRACT:
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(propylene glycol) diamines tend to phase separate under these conditions and polyamide-6,6 could not be so modified. The resultant poly(etheramide) segmented block copolymer has improved impact performance, reduced modulus and lower glass transition as contrasted with the non-modified polyamide-6,6.
