摘要：

The GPC concentration effect has been investigated in THF at 25 degree C for polydispersed PVC samples. The experimental results show that the GPC elution volume is a linear function of concentration. A new simplified model theory proposed by Song for concentration dependence of GPC elution volumes agrees well with the experiments. The second Virial coefficients of PVC determined from GPC concentration effect by the calibration of the polydispersed PVC samples are 0. 84 multiplied by 10** minus **3, 1. 0 multiplied by 10** minus **3 and 1. 32 multiplied by 10** minus **3, respectively.
