Abstract
Hydroxy-terminated poly(2,2-dinitropropyl)polynitroorthocarbonate prepolymers of the formula <IMAGE> which are prepared by reacting bis(2,2-dinitropropyl)dichloroformal with a diol of the formula <IMAGE> wherein n>1, and wherein W, X, Y, and Z vary independently and are F or NO2, and wherein -A- is -CH2-, -CH2CH2-, -CH2CH2CH2-, -CF2-, -CF2CF2-, -CF2CF2CF2-, -CF2CF2CF2CF2-, -CH2OCH2-, -CH2OCH2OCH2-, -CH2OCF2OCH2-, or -CH2N(NO2)CH2-. These prepolymers are reacted with curing agents (e.g., polyisocyanates) to form energetic polymeric binders.
