This article presents a convenient method for synthesizing segmented poly(ether ester amide)s (PEEAs) by polycondensation and chain extension. A nylon-6 oligomer prepared from ε-caprolactam and ethanolamine through ring-opening polymerization was polymerized with adipic acid and diglycol to prepare PEEA prepolymers (PrePEEAs) with ether linkages and amide contents ranging from 20 to 60 mol%. Chain extension of the PrePEEAs was conducted at 200°C using 2,2′-(1,4-phenylene)-bis(2-oxazoline) and carbonyl biscaprolactamate as combination chain extenders. The chain-extended PEEAs (ExtPEEAs) were characterized by viscometry, gel permeation chromatography, FT-IR, 1H-NMR, differential scanning calorimetry, thermogravimetric analysis, wide angle X-ray diffraction, and tensile testing. Results show that incorporation of nylon-6 segments yields semicrystalline ExtPEEAs and that introduction of ether linkages improves the flexibility of the resultant polymers. ExtPEEAs showed Tm from 107.6 to 137.3°C, good thermal stability with initial decomposition temperatures above 337.3°C, and tensile strengths of up to 27.4 MPa with strains at break ranging from 231.24 to 1052.52%.
