Abstract: Copolymerizations of propylene and butadiene in various ratios with two kinds of supported catalysts, i.e. TiCl4/MgCl2/AlEt3 and TiCl4/MgCl2/AlEt3/ethyl Bonzoate(EB). have been investigated. The results show that these two catalysts are quite effective for propylene-butadiene copolymerization but behave in different features. Characterizations of the copolymerization products by solvent extraction, IR, 13C NMR, X-ray diffraction and DTA show that blocked propylene-propylene and butadiene-butadiene sequences exist in polymer chain and the butadiene units are exclusively in trans-1,4 configuration.
