The polarization characteristics of the integrated profiles for 18 pulsars were measured at 102.5 MHz, using a special technique based on Faraday rotation in the interstellar magnetic field. Linear polarization percentage and position angle variation forms were obtained as a function of the pulse phase. A comparison of these data with those at higher frequencies was made. The linear percentage for the pulsars measured increases at metre wavelengths as compared with the decimetre ones. As well as at higher frequencies, the discontinuities ≡90° in position angle behaviour across the longitude frequently occur at 102.5 MHz, due to the existence of orthogonally polarized modes of radiation. The values of RM and the longitudinal component of the galactic magnetic field were measured in the direction of 5 pulsars. The results of the observations are discussed.
