The soft X-ray emission from plasma produced in polyacetal and polyethylene capillary discharges excited by current pulses 100 ns full-width half-maximum (FWHM), 50 ns risetime, and peak currents up to 60 kA has been studied. Time-resolved spectra show that intense C VI line emission dominates in the polyethylene discharges, peaking shortly after the maximum of the current and vanishing before the end of the current pulse. Polyacetal capillary spectra are dominated by OVI lines and show weak CVI emission. Plasma density and temperature for the polyethylene discharge were derived from the Stark broadening of C VI Balmer lines and the relative intensities of C VI and CV lines. A short (5 ns FWHM) pulse of energetic beam electrons was detected in coincidence with the onset of the discharge
