Epoxy resins are a class of reactive prepolymers, which are extensively used for polymeric matrices for fiber reinforced composites due to their outstanding mechanical property, heat resistance, and electrical resistance. Epoxy resins may be cross-linked wither with themselves thourgh catalytic homopolymerization, or with a wide range of co-reactants such as multifunctional amines, anhydrides, phenols, alcholols, etc. In this study, we investigate the thermal crosslinking behavior and mechanism of an epoxy compound, which is synthesized from 4,4'-(1-methylethylidene)bisphenol, chloromethyl oxirane, 2-propenoate, and 2-propenoic acid 1,6-hexanediyl ester, with glycidyl methacrylate (GMA) in various proportions. The thermal crosslinking behavior of the epoxy acrylate compound with GMA were characterized using differential scanning calorimetry. The crosslinking mechanism was investigated by monitoring FT-IR spectra as a function of temperature. |
