Using polarimetric radio profiles of 84 pulsars at a wavelength of 6 cm, we present a correlation between the polarization and characteristic age of pulsars. Considering the large error connected with the value of the characteristic age, we speculate about the possibility of identifying young pulsars through their polarimetric properties. Using this method we have identified more than 20 possibly young pulsars including some with a relatively high characteristic age. Of these objects, seven have already been proposed to be associated with supernova remnants. For the remaining pulsars we find a number of candidates for associated faint SNRs and present one of them. This shows that this method can be used as an additional independent indicator for the youthfulness of pulsars.
