Poly(imide-amide)-poly(ethylene adipate) hybrid networks. I. Nanostructure and segmental dynamics

Original language description

Segmental dynamics at 200-500 K and nanometer-scale structure were studied by SAXS, DSC and creep rate spectroscopy (CRS) techniques in two series of poly(ethylene adipate)-crosslinked poly(imide-amides) with regularly varied compn. and different lengthsof PEA crosslinks (Mn=1.300 and 2.700 g mol-1). The crystn. ability was obsd. in networks with longer PEA crosslinks. Shorter PEA crosslinks induced non-cryst., nanostructured PIA-PEA networks. Combined DSC/CRS anal. indicated the pronounced heterogeneity of segmental dynamics in the latter networks. The wide dispersions of motional activation energies within the glass transitions were found by DSC, and manifestation of a few constituent segmental motions was shown in the creep rate spectra. The obsd.
