摘要: We examine the relevance of strong-fragile classification scheme for glass-forming polymeric systems using results from Brillouin and photon correlation spectroscopy. The dynamics salt doped polypropylene oxide (PPO) have been investigated in relation to induced local structural ordering. It is accomplished by forming complexes NaCF3SO3-PPO which cations act as transient cross-links between chains. amount depends on concentration temperature. This allows a test suggested properties some characteristics relaxation function such its non-exponential time decay non-Arrhenius temperature dependence.
