ew rare earth catalyst system suitable for preparing bi-and ter-copolymers of styrene(St) and conjugated dienes has ho report first in our laboratory. In this paper
the copolymerization of St and butadiene (Bd) with the L3Ln' nL'-RX- Rm'AIHM3-m catalyst system was further studied in detail on the effects of ligands
rare earths
alkyl aluminums
the third components etc. on the copolymerzation activihes
molecular weight and stereospeficities of the copolylners. The sequence structures of the copolymer were thoroughly in-vestigated by 13C-NMR spectrum. Some of the experimental results were tentatively explained by the mechanisms of π-allyl and back-biting coordination.
