摘要：

Low molecular weight organic glasses were made by melt mixing two crystalline solids: bisphenol A and various bispyridines. Stable glasses were obtained because of intermolecular hydrogen bond formation between phenol and pyridine groups. The composition dependence of the Tg of the mixtures shows a very strong and positive deviation from the behavior of ideal copolymers or ideal polymer blends. Moreover, the strong influence of the structure of the low molecular weight compounds on the Tg of the mixture can be adequately described by empirical relationships, which are known in the field of polymers.
