The results of a polarization analysis of rocoses (radio objects with a continuous optical spectrum) are presented, using observations from the 2.6 m telescope of the Crimean Astrophysical Observatory. It was considered that polarization was detected of the probability of obtaining measured values was less than 0.01, for a specified rms error value, and polarization was detected in 11 rocoses. These data, combined with other available measurements, reveal 28 highly polarized (greater than or equal to 5%) and 8 weakly polarized (less than or equal to 3-4%) rocoses. Two of the weakly polarized objects are believed to be highly polarized rocoses during a phase of minimal polarization, due to the strong correlation between strong optical polarization and the presence of a compact radio component. Strongly polarized rocoses show some characteristics of highly polarized quasars such as rapid and strong variability, steep optical spectra, and compact radio-emitting structures.
