• The excluded volume effect on the radius of gyration of chain polymers is calculated by assuming that the intramolecular energy is represented by the product of the binary cluster integral of polymer segments and their contact probability. The expansion coefficient α of polymer can be given by the expression: α^5-α^3=(134/105)zα^x, X=0.4∼1.0, where z is the usual interaction parameter of segments. In this calculation if the expansion coefficient α_<ij> is taken to be the increasing function of |j-i|, it becomes positive. The values of α obtained by this calculation are close to that of the previous theory by equivalent ellipsoid polymer model in the range practically usefull (1≲α^2≲3), and they are almost in coincidence with the result of the second or third order perturbation theory for very small |z|.
