ABSTRACT:
Hydroxy-terminated poly(2,2-dinitropropyl)polynitroorthocarbonate prepolys of the formula ##STR1## which are prepared by reacting bis(2,2-dinitropropyl)dichloroformal with a diol of the formula ##STR2## wherein n>1, and wherein W, X, Y, and Z vary independently and are F or NO.sub.2, and wherein --A-- is --CH.sub.2 --, --CH.sub.2 CH.sub.2 --, --CH.sub.2 CH.sub.2 CH.sub.2 --, --CF.sub.2 --, --CF.sub.2 CF.sub.2 --, --CF.sub.2 CF.sub.2 CF.sub.2 --, --CF.sub.2 CF.sub.2 CF.sub.2 CF.sub.2 --, --CH.sub.2 OCH.sub.2 --, --CH.sub.2 OCH.sub.2 OCH.sub.2 --, --CH.sub.2 OCF.sub.2 OCH.sub.2 --, or --CH.sub.2 N(NO.sub.2)CH.sub.2 --. These prepolymers are reacted with curing agents (e.g., polyisocyanates) to form energetic polymeric binders.
