Synthesis and Properties of Epoxy Resin Modified with Novel Reactive Liquid Rubber-Based Systems

Abstract: In this work, the influence of the new epoxy-containing liquid rubber-based modifiers on the thermal and mechanical properties of the cured epoxy resins was investigated. The epoxy-functional polybutadienes obtained via the conventional epoxidation reaction or catalytic hydrosilylation have been successfully applied for modification of commercially available epoxy resin to modulate its mechanical properties. Different locations of oxirane rings in the polybutadiene chains revealed a significant impact of the r… Show more

“…[1][2][3] However, due to their high crosslinking density, 4 cured epoxy resin is brittle, which limits its application. 5 To overcome this issue, a toughening agent for epoxy matrix is added to the epoxy compositions. 6 Toughening agents such as elastomer with rubbery core/shell, 7 nanoparticles, 8 thermoplastic polymers, 9,10 and flexible polymers, 11,12 increase the chain flexibility of the epoxy matrix.…”

“…thereby introducing the flexible rubber chain into the crosslinking structure of the epoxy resin and improving its toughness 9 . By processing different toughening technologies, LSBR is fully dispersed and attached in the epoxy resin system, thus improving the fracture toughness and heat resistance of the cured epoxy resin, and reducing the viscosity of the system to a certain extent 10,11 . LRs are economical and can be easily introduced into epoxy resins, 12 such as carboxyl‐terminated liquid nitrile‐butadiene rubber (CTBN), 13 hydroxyl‐terminated liquid nitrile‐butadiene rubber (HTBN), 14 and hydroxyl‐terminated liquid polybutadiene (HTPB) 15 .…”
