The polymerization behaviour of isoprene conducted by using a novel C60 Supported neodymium catalyst system Nd(nhph)3(Nd) C60 X(X) Al( i Bu) 3(Al)was investigated.It revealed that this catalyst system in hydrogenated gasoline was a homogeneous catalyst
and the molar ratios of Al/Nd and X/Nd seriously affect catalytic activity
molecular weight and its distribution. The formation of active center complexes and the catalytic activity have well stability with the aging time and aging temperature.The intrinsic viscosity of polymer obtained is from 1to 4 dL/g;the molecular weight distribution is from 2 to 4.The content of cis-1
