Abstract
We studied cross-linking, water resistance, and impedance characteristics of polymeric compositions based on epoxydiane and maleinized petroleum polymeric resins. It is shown that epoxy and petroleum polymeric components interact at temperatures of 150°C and higher to form cross-linked copolymers. The gel-fraction content of the composition increases with the acid number of the petroleum polymeric component. Small amounts of tertiary amine enhance the efficiency of its cross-linking. The water resistance and protective properties of epoxy-petroleum polymeric compositions improve as the acid number of petroleum polymeric resins increases and the content of the liquid fraction decreases.
