N2 - Nanostructured self-assembled and high-performance epoxy/epoxidized poly(styrene-block-butadiene-block-styrene) block copolymer blends with 55 mol% epoxidation degree [eSBS55]- 0,5,10 and 20 phr- 4, 4′diaminodiphenyl methane (DDM) material were successfully synthesized by using solvent casting method. The role of the highest epoxidized SBS (eSBS55) as a modifier and its concentration on the effect of nanostructured morphology, viscoelastic properties, reaction induced phase separation and thermal degradation kinetics of epoxy/eSBS55system were investigated in detail. Various theoretical models such as Coats-Redfern method, Broido method and Horowitz- Metzger method were applied for the first time on epoxy/eSBS systems to calculate the thermodynamic parameters and correlate experimental results. These highly enhanced viscoelastic & thermal properties and nanoscale morphology of as synthesized novel epoxy/eSBS55 material have proved that ‘eSBS55’is an outstanding modifier to epoxy resin for creating superior high-performance properties required for various coating and structural applications such as in aircrafts, floorings, automobiles and constructions.
