Abstract
A study has been made of the dynamic mechanical properties of an epoxy composition based on the diglycidic ether of resorcinol and 2,6-diamino pyridine modified with polyester urethane rubber (grade A-2). The dependence of the relaxation spectrum parameters on the modifier concentration has been investigated. The changes observed are associated with the implantation of fragments of the rubber molecules into the polyepoxide network.
