Abstrakt:	The copolymers of functionalized polydimethylsiloxane (PDMS) and epoxy resin were prepared by varying the concentration of PDMS with an objective to produce products with high-performance properties. These copolymers were cured using polyamide as a curing agent and characterized by FT-IR. The thermal properties and completion of curing were checked by DSC. The copolymers were evaluated for electrical and mechanical properties. The dielectric strength of the material increases with decrease in dissipation loss and dielectric constant. The mechanical properties were improved by 30–40 percent. The main objective was to reduce the brittleness and improve impact strength of epoxy systems. [ABSTRACT FROM AUTHOR]
