We present multi-epoch, high signal-to-noise spectropolarimetry of the Raman-scattered emission lines of five S-type symbiotic binaries: CD-43 14304, Hen 1242, M 1-21, SY Mus, and V455 Sco. The Raman-line polarizations and magnitudes are used to estimate orbital parameters for these systems. Two of the five systems (CD-43 14304 and SY Mus) have published radial-velocity orbits, which agree with the spectropolarimetric solutions. The physical parameters of the programme stars are consistent with the period-spectral-type relation of Muerset & Schmid (1999A&AS..137..473M).
