The tritiated alcohol quench method was used for determining the tritium number average molecular weight [M_n]_T of polybutadiene prepared wtih lanthanide catalysts.The change in [M_n]_T Wtih conversion for different lanthanide catalysts was studied. It was found that for certain lanthanide catalytic systems the values of [M_n]_T of polybutadiene were approximately equal to those obtained by using osmometry technique. It was shown that the tritium end group analysis could be used for determining Mn of polybutadiene prepared with lanthanide catalysts.
