摘要: Borel summations on the sixth‐order perturbation series for polymer mean square end‐vector expansion factor α2 by Muthukumar and Nickel are compared with computationally simpler second order in e renormalization group crossover description of excluded volume dependence α2. An essential feature comparison is use same cross over variables definitions both treatments. The agreement found to be very good.
