The numerical solution of a system of differential equations 
for the concentrations of the reaction system's macromolecules, which 
describe the synthesis of diene rubber on a neodymium-containing catalyst 
system, has been obtained. The influence of the chain-transfer reactions 
on the number distributions of the monomer links of macromolecules 
with an assigned number of active sites has theoretically been investigated.
