| Abstract: | tyrene-ethylene copolymers were synthesized by copolymerization of styrene and ethylene using the MgCl2/TiCl4, NdCl3/AlEt3 catalyst and characterized by 13C-NMR, IR, DMA and solvent extinction fractionation . The results show that the catalyst exhibits high activity for the copolymerization of styrene and ethylene and the obtained copolymers are composed of various comonomer sequences . The mechanical properties of blends consisted of polystyrene and the copolymers are much better than those of polystyrene. |
