Abstract : In accordance with this invention, there is provided a novel compound which acts effectively as a plasticizer for propellant compositions without the attendant problems of plasticizer migration which occur during propellant storage. The plasticizer of this invention is a carbamic acid ester. The primary object of this invention is to provide a novel carbamic acid ester having a particular molecular structure. Another object of this invention is to provide a novel solid propellant composition that produces only minimum amounts of plasticizer migration during its shelf-life. Still another objective if this invention is to provide a novel carbamic acid ester that finds particular utility as an internal plasticizer for solid propellant compositions.
