Compounds of the formula: ##STR1## wherein one X is COOR, CH.sub.2 COOR, CH(COOR).sub.2, CONHR, CH.sub.2 CONHR, or CN

Anti-inflammatory carboxy pregnane derivatives

Derivatives of prednisolone of the formula ##STR1## wherein CR.sub.1 is C.dbd.O, .alpha.-HCOH, .beta.-HCOH, or a mixture of .alpha.-HCOH and .beta.-HCOH CR.sub.2 is HC(OH) OR.sub.6 or HCO when CR.sub.1 is C.dbd.O;

Anti-inflammatory prednisolone steroids

A polyurethane-quartz laminate suitable for aircraft radomes. Controlled amounts of a mixture of unpolymerized 4,4 diphenyl methane diisocyanate (MDI) and 2,4 toluene diisocyanate (TDI) are polymerized with ethylene glycol at a preselected temperatures and periods to produce a polymeric resin of relatively few nonpolar isocyanate groups. The resin is impregnated and cured in layers of quartz cloth to form a relatively high strength composite or laminate having a low dielectric constant.
