The results of a measurement of the polarization parameter Ρ in elastic π~ ρ scattering at energies of 490 and 600 MeV are presented. The experiment was performed in the 7r-meson channel of the LINP synchrocyclotron using a polarized proton target and spark chambers with magnetostrictive information output. The data obtained make it possible to reduce the phase analysis uncertainty and increase the accuracy of the determination of the parameters of the Sn, Pn, and Dl3 resonances.
