For step-growth polymer systems of general type “AfiBgi”, a fast method is derived to compute the MSD and the MWD. The figure shows the full MWD curves of system “A1B1 + B1 + A2 + B3” with pA[gel] = 0.969877 at pA = 0.964, 0.967, 0.969. Blue: calculated using recurrence scheme. Red: calculated using analytic approximation.
