Synthesis and Characterisation of Polyamidoamine-cured DGEBA-siloxane Interpenetrating Polymer Network

A commercially viable polydimethylsiloxane(PDMS)diglyceryl ether of bisphenol-A (DGEBA)interpenetrating network from hydroxyl terminated PDMS and DGEBA was synthesised.Epoxy resin was thoroughly mixed with PDMS to get a prepolymer. The interpenetrating polymer network has better electrical and thermal characteristics with high impact resistance compared to the virgin epoxy system.
