Studies on some acrylamido polymers and copolymer as stabilizers for nitrocellulose

para-Phenylene diamine was reacted with diethylmalonate and the product was reacted with acryloyl chloride to obtain the corresponding acrylamido malonanilide monomer. para-Nitro aniline was also reacted with acryloyl chloride to obtain the corresponding monomer. The two monomers were homopolymerized and then copolymerized, The obtained homopolymers and the copolymer were mixed with nitrocellulose and evaluated using thermal analysis and Bergmann-Junk techniques as propellant stabilizers in comparison with the common stabilizer, centralite 1. It was found that the homopolymer containing the p-nitro group is a superior stabilizer. (C) 2002 Wiley Periodicals, Inc.
