Intrinsic polarization parameters (p and Theta) for 10 Cepheid stars were studied in relation to the light-curve phase Phi. It is shown that the intrinsic polarization p is small, and increases slightly during the period. The polarization parameter Theta, however, reaches two prominent peaks during the same period, with one peak sharper than the other. The similar characteristics of the curves P(Phi) and Theta(Phi) for all 10 of the stars confirmed the effectiveness of the technique for evaluating the interstellar polarization component of Cepheid stars. The polarization curves are superimposed on the light-curve phase variations in a table.
