摘要

Abstract

Two kinds of aliphatic alternating polyesteramide prepolymers were prepared through melt polycondensation from

'-bis(2-hydroxyethyl)-adipamide and adipic acid or sebacic acid. Chain extension of them was conducted with 2

2′-(1

4- phenylene)-bis(2-oxazoline) and adipoyl biscaprolactamate as combined chain extenders. The chain extended polyesteramides (ExtPEAs) were characterized by IR

H-NMR

differential scanning calorimetry

thermogravimetric analysis

wide angle X-ray scattering

tensile test and enzymatic degradation. The results showed that the ExtPEA(4

)s were mainly constituted with the diester adipamide alternating units. ExtPEA(4

4) and ExtPEA(4

8) had

of 83.8℃ and 85.8℃ and initial decomposition temperature above 310.0℃. They crystallized similarly as Nylon-66 did and were flexible thermoplastic materials with tensile strength up to 25.64 MPa and strain at break up to 737%.
