In this paper a new relation between the second virial coefficients A

（?）

and (dV

/dC)

→0=K

was derived from proposed model theory of concentration effects in GPC for mono-and poly-dispersed polymers. Based on this relation a new method for determination of second vifial coefficients from the combination of (dV

/dC)

→0=K

（?）

and K

measurements was proposed.The values of A

for mono-and poly-dispersed polystyrenes with molecular weight range from 10

to 10

in good and theta solvents were determined by proposed method. Results show that their values of A

are in agreement with those obtained by light scattering.
