THE INTERACTIONS OF COMPONENTS IN POLYETH YLENE EPOXY-RESIN INTERPENETRATING NETWORKS

The interactions between components have been studied in the course of viscoelastic deformation of the polyethylene-epoxy resin interpenetra ting networks. The contribution of interactions into elastic character istics of interpenetrating network is shown to depend upon phase state of the constituents of the system. It is proposed to calculate this c ontribution by representing the spectrum of relaxation times in terms of the sum of three components, the term associated with the interacti on of components being added to the sum of the spectra of relaxation t imes of individual constituents. It is shown that with due allowance f or interactions between the components, the calculated dependences rea sonably fit the experimental dependences of the moduli of interpenetra ting networks upon their composition.
