Toughened epoxy adhesive modified with acrylate based liquid rubber

Toughened epoxy adhesive modified with acrylate based liquid rubber The adhesive and mechanical properties of epoxy resins modified with carboxyl terminated poly(2‐ethylhexyl acrylate) (CTPEHA) liquid rubber have been investigated as a function of the concentration of liquid rubber. CTPEHA was synthesized by the bulk polymerization technique. CTPEHA oligomer was prereacted with the epoxy and the modified epoxy networks were made by curing with an ambient temperature curing agent. The modified epoxy networks were evaluated with respect to their adhesive and mechanical properties. The optimum properties were obtained at about 10–15 phr (phr stands for parts per hundred parts of epoxy resin) concentration of modifier. Fracture surface analysis by optical microscopy (OM) indicates the presence of two phase microstructures. © 2000 Society of Chemical Industry http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Polymer International Wiley

Abstract

The adhesive and mechanical properties of epoxy resins modified with carboxyl terminated poly(2‐ethylhexyl acrylate) (CTPEHA) liquid rubber have been investigated as a function of the concentration of liquid rubber. CTPEHA was synthesized by the bulk polymerization technique. CTPEHA oligomer was prereacted with the epoxy and the modified epoxy networks were made by curing with an ambient temperature curing agent. The modified epoxy networks were evaluated with respect to their adhesive and mechanical properties. The optimum properties were obtained at about 10–15 phr (phr stands for parts per hundred parts of epoxy resin) concentration of modifier. Fracture surface analysis by optical microscopy (OM) indicates the presence of two phase microstructures. © 2000 Society of Chemical Industry
