Network Polymers Based on Epoxy Oligomers and Dicyandiamide

Abstract

The formation of network polymers by curing epoxy oligomers with dicyandiamide was investigated. The oligomers had the structure It was shown that the reaction between hydroxyl and epoxy groups is important in this process. The strength-deformation properties of the network polymers obtained were studied. Calculations of elastic active network chains were carried out by the method of branching processes. Good agreement was obtained between calculated and experimental data.
