Abstract: The structures and compositions of the copolymers of diaikyl fumarates such as PDiPF/ DnPF, PDiPF/DnBF, PDiPF/DnAF, PDiPF/DnHFand PDiPF/DEHFwere characterized by 1H NMR.The effect of compositional ratio on the strength and strain as well as dynamic mechanical properties of these copolymers was investigated.The results show that the elongation of break of these copolymers increases significantly with increasing content of DRFs(DnPF, DnBF, DnAF, DnHF, DEHF), while tensile strength decreases.The a and β transition peaks shift to lower temperatures with increasing content of DRFs.The thermal properties and other properties of the copolymers were also clarified.
