Alternating polyesteramides based on 1,4-butylene terephthalamide: 4. alternating polyesteramides based on glycols (4NT glycol) [PDF]

, 1998
Polyetheresteramides (PEEAs) have been synthesised in the melt from 1,4-butylene terephthalamide and ethylene or propylene glycols. The ethylene glycols were ethylenediol, diethylene glycol, triethylene glycol and tetraethylene glycol.
