In this study, 1,1′-bis[4-(2,3-epoxypropoxyphenyleneininomethyl)]-2,2′-dimethylbiphenylene (BMPE) was synthesized and characterized by FT-IR and NMR. The effect of 1,1′-bis[4-(2,3-epoxypropoxyphenyleneininomethyl)]-2,2′-dimethylbiphenylene (BMPE) content on mechanical and thermal properties of its blends with diglycidyl ether of biphenol A (DGEBA) was investigated by DSC and polarizing optical microscope. The improvement of mechanical properties of DGEBA modified with 1,1′-bis[4-(2,3-epoxypropoxyphenyleneininomethyl)]-2,2′-dimethylbiphenylene (BMPE) was achieved without reducing thermal resistance. Tensile strength and elongation of DGEBA-BMPE (8:2) increased, and the glass transition temperature increased compared with the DGEBA-DDS blend.
