Abstract
Abstract Unsymmetrical nitro and fluoronitro acetals of the formulas ROCH(CH.sub.3)OR' wherein R≠R', but wherein both R and R' are selected from the group nsisting of -CH 2 CXY(NO 2 ), - CH 2 C(NO 2 ) 2 CH 3 , -ch 2 cuvcxy(no 2 ), and -CH 2 CUVCWZCXY(NO 2 ), wherein X and Y vary independently and are selected from the group consisting of F and NO 2 , and wherein U, V, W, and Z vary independently and are selected from the group consisting of H, F, and NO 2 , are useful as energetic plasticizers in rocket propellants or explosives.
