摘要：

The results on molecular mobility in epoxy amine crosslinked polymers at segmental (alpha process) and local (beta process) levels are analyzed. The effect of intrachain and interchain rigidities on the above processes is considered, where the intrachain rigidity is measured with the use of flexibilizing agents and the interchain rigidity is dependent on the intermolecular-interaction intensity, which is governed by the introduction of plasticizing agents. Both modes of molecular mobility in the crosslinked polymers show a cooperative character that controls the dissipation energy of the corresponding relaxation process. The correlation between the above processes and the elastic, strength, and relaxation characteristics of the epoxy amine crosslinked polymers is studied. Molecular mobility is shown to exert an inverse effect on the relaxation and dissipative characteristics of the network polymers.
