Epidian 5

An Oligomer with Terminal Unsaturated Double Bonds Based on Epidian 5 and Ethylacrylic Acid

An oligomer with terminal unsaturated double bonds (unsaturated oligomer, UO) has been synthesized from epoxy resin Epidian 5 and ethylacrylic acid. The impact of the catalyst nature, temperature, and reaction duration on the progress of the reaction between the resin and the acid has been studied. A synthetic technique is proposed for producing the UO. The UO has been characterized by chemical and FTIR-spectroscopic analyses. The UO has been examined in the cross-linking processes with oligoesteracrylates TGM 3 and MGP 9 as well as unsaturated polyester PE 246.
