Abstract:

Liquid polybutadiene with desirable 1,2-units content was synthesized by Co(naph)2-Al2(C2H5)3Cl3-P(OPh)3 catalyst system. It was shown that liquid polybutadiene having adequate 1,2-unit content (vinyl=35%—40%), molecular weight(Mn=700—3500), and acceptabele conversion(≥55%) can synthesized after optimizing polymerization conditions.

Key words: Liquid polybutadiene; Cobalt; Triphenyl phosphate
