AbstractThe high trans - configuration butadiene - isoprene copolymers have been synthesized in the presence of TiCl4/MgCl2 - Al ( i - Bu)(3) catalysts when butadiene mole content in the feed are between 0.055 similar to 0.148. The sequence structures of trans - butadiene - isoprene copolymers have been determined by C-13 NMR spectrometry. The dyad distributions, composition and number - average sequence length of these copolymers are calculated on the basis of assignment of C-13 NMR spectra. The results indicate that the sequence distributions of monomer units in copolymers follow first - order Markov model according to calculations. The products are sequence - irregular copolymers.
