V originále
Broadband dielec. relaxation spectroscopy (DRS), thermally stimulated depolarisation currents (TSDC), differential scanning calorimetry (DSC) and to a lesser extent water uptake measurements, were employed to investigate mol. mobility, morphol. and crystn./melting events of PEG in poly(imide-amide)-polyethylene glycol hybrid networks (PIA-PEG) with short (M n=1000 g/mol) and long (M n=3400 g/mol) PEG crosslinks. The results obtained suggest long range connectivity of the PEG component in the hybrids with short PEG crosslinks at PEG content higher than 40 wt% and in these with long PEG crosslinks at PEG content higher than 20 wt%. Crystn. of the PEG component is obsd. by DSC in the hybrids with the longer crosslinks at sufficiently high content of PEG, only. The glass transition temp., T g, of PEG component in the hybrids with the shorter PEG crosslinks is shifted to higher temps. compared to that of the hybrids with longer PEG crosslinks, while suppression of the glass transition of the PEG component is obsd. in the hybrids with the shorter PEG crosslinks at PEG content lower than 40 wt%. The results are discussed in terms of constraints to segmental motion of the PEG crosslinks, imposed by fixed PEG chain ends on the rigid PI chains.
