Abstract : In accordance with this invention, there is provided a noval compound which acts effectively as a propellant plasticizer without the attendant problems of plasticizer migration that often occur during propellant storage. The plasticizer of this invention is carbamic acid ester. The primary object of this invention is to provide a novel carbamic acid ester plasticizer 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 storage shelf-life. Still another object of this invention is to provide a novel carbamic acid ester that finds particular utility as an internal plasticizer for solid propellant compositions.
