Monomer sequence distribution of copolymers of butadiene and isoprene prepared with lanthanide complexes LaCl2-C2H5OH-Al(C2H5)2 was determined by 13C-NMR spec-trometry.The dyad distribution and number-average sequence length of these copolymers were quantitatively determined. The results show that sequence distribution of monomer units in copolymers prepared with Nd
