Abstract:

This report contains a compilation of data comparing geminal and vicinal difluoramino-containing plasticizers and copolymers. The plasticizers studied are 1, 2, 3-tris1,2 -bisdifluoraminoethoxy propane and 1,2,3-tris2,2 bisdifluoraminopropoxypropane. The copolymers are acrylic acid copolymers of both 2,3-bisdifluoramino -propyl acrylate and 2,2-bisdifluoraminopropyl acrylate. Data are presented for the monomeric materials, copolymers, binders, and propellants. The data indicate that the vicinal and geminal materials behave similarly in many respects. The major disadvantage of the geminal NF-containing materials is their greater impact sensitivity. The main area in which the geminal materials show an advantage is seen in those tests related to storage stability. These tests include vacuum gas evolution and adiabatic self-heating. Data on fissuring time show that the geminal copolymers are as good as, if not better than, the best vicinal copolymers made to date. The geminals also have higher burning rates than the corresponding vicinals however, the increase observed in the propellant is small. Author
