Abstract
Diols of the general formula, R(OH).sub.2, wherein R is an alkylene radic and iminodiols of the general formula, R'N(R'OH).sub.2, wherein R' is an aryl or alkyl radical and R' is an alkylene radical, with melting points of less than 60.degree. C (140.degree. F) are effective dispersing aids for the bonding agent MT-4. MT-4 which functions as an interfacial bonding agent is prepared by reacting together 2.0 moles of tris 1(2 methylaziridinyl)phosphine oxide, 0.7 mole adipic acid, and 0.3 mole tartaric acid. The specified dispersing aids react to become a part of the binder matrix without causing degradation of physical properties or nullification of the functions of MT-4. The specified dispersing aids for the bonding agent MT-4 were found to be particularly effective to ensure uniform coating of solids in solid propellants employing a hydroxy-terminated polybutadiene binder system while not imparting negative side effects that the dispersing adjuvant of 'added' water causes.
