Analysis of the low resolution UV(IUE) spectra of 15 hot post-AGB candidatesis presented. The UV(IUE) spectra of 10 stars suggest partial obscuration ofthe hot stars due to circumstellar dust. The reddened continua of these 10stars were used to model and estimate the circumstellar extinction. Thecircumstellar extinction law was found to be linear in $\lambda^{-1}$ in thecase of IRAS13266-5551 (CPD-55 5588), IRAS14331-6435 (Hen3-1013),IRAS16206-5956 (SAO 243756), IRAS17074-1845 (Hen3-1347), IRAS17311-4924(Hen3-1428), IRAS18023-3409 (LSS 4634), IRAS18062+2410 (SAO 85766),IRAS18371-3159 (LSE 63), IRAS22023+5249 (LSIII +5224) and IRAS22495+5134 (LSIII+5142). There seems to be no significant circumstellar extinction in the caseof IRAS17203-1534, IRAS17460-3114 (SAO 209306) and IRAS18379-1707 (LSS 5112).The UV(IUE) spectrum of IRAS12584-4837 (Hen3-847) shows several emission linesincluding that of HeII. It may be a massive young OB-supergiant or a low massstar in the post-AGB phase of evolution. IRAS16206-5956 (SAO 243756) and IRAS18062+2410 (SAO 85766) show variability in the UV which in addition to stellarpulsations may be attributed to a dusty torus in motion around the hot centralstars. The UV spectrum of the bipolar PPN, IRAS17423-1755 (Hen3-1475) indicatesthat the central B-type star is obscured by a dusty disk. The stars were placedon the log g$-$log T$_{\rm eff}$ diagram showing the post-AGB evolutionarytracks of Sch\"onberner. Terminal wind velocities of the stars were estimatedfrom the CIV and NV stellar wind features. The presence of stellar wind in someof these stars indicates ongoing mass-loss.
