PURPOSE:The titled adhesive, containing a diisocyanate, polydiene glycol and specific polyfunctional compound, and suitable for bonding a polydiene based propellent body to a restrictor or an insulator containing a liner of rocket motors. CONSTITUTION:An adhesive, containing (A) a diisocyanate, (B) a polydiene glycol obtained by anionic polymerization of a diene compound, and having 1.8-2.1 number of OH groups and 1,000-5,000 number-average molecular weight, (C) an isolable compound containing 3 or 4 one ore more functional groups of OH groups and/or NH2 groups in one molecule, (D) a compound having 1.8-2.1 number of one or more functional groups of OH groups and/or NH2 groups in one molecule and <=900 number-average molecular weight, and suitable for bonding a propellent body using a polydiene having terminal OH groups as both a fuel and a binder to a restrictor or insulator containing a liner of rocket motors.
