Methods MWD polymers by contacting generating functions and formulas Stehfest and Papoulis adapted for ionic polymerization catalyst system with two types of active sites, and with the chain transfer to polymer in a cascade of stirred reactors. The calculated MWD compared with the solutions obtained by direct integration of material balances of the polymer chains, recorded with long-chain approach.
