Abstract:

Nitroso rubber, a copolymer of trifluoronitrosomethane and tetrafluoroethylene, has been made in pilot-plant quantity by the Thiokol Chemical Corporation under Army Contract DA19-129-AMC-69. Research compounding studies have been made on this pilot-plant production rubber. A variety of cross-linking vulcanization agents were investigated, the most effective of which was triethylene-tetramine. Of a series of reinforcing fillers used, the best physical properties were obtained with HiSil 303. However, a silicone-treated HiSil 233 gave comparable results. The curing characteristics of the nitroso rubber made in the pilot plant at the Thiokol Chemical Corporation were different from those of the material prepared in the laboratory of the Minnesota Mining and Manufacturing Company. based on the research compounding studied made, there is no indication that rubber compounds having excellent physical properties can be made from the Thiokol Chemical Corporation nitroso rubber.
