Patent number: 4245085Abstract: New crosslinked 1,2,4-oxadiazole elastomers have been prepared by thermally condensing (a) monomer having the formula H.sub.2 N(HON)C-R-Q, wherein Q is a triazine ring-forming group such as nitrile or amidine, or (b) a mixture of said monomer with R[C(NOH)NH.sub.2 ].sub.2, with R in these formulas standing for a bivalent organic radical having the formula--(CX.sub.2).sub.p --, or --CFY(OCF.sub.2 CFY).sub.m O(CX.sub.2).sub.p O(CFYCF.sub.2 O).sub.n CFY--wherein X is fluorine or hydrogen, Y is fluorine or trifluoromethyl, p ranges from 1 to 18, and m+n ranges from 2 to 7. In the monomer charge, the overall proportions of amidoxime groups to triazine ring-forming groups varies depending on the extent of crosslinking desired in the final polymer.The heat and chemical resistant elastomers disclosed can serve, for instance, as adhesives, caulking compounds, channel sealants, fuel tank liners.Type: GrantFiled: April 9, 1979Date of Patent: January 13, 1981Inventors: Robert A. Administrator of the National Aeronautics and Space Administration, with respect to an invention of Frosch, Robert W. Rosser, Ibrahim M. Shalhoub, Hanoi Kwong

Patent number: 4242498Abstract: New crosslinked elastomeric polytriazines have been prepared by a 4-step procedure which consists of: (1) forming a poly(imidoylamidine) by the reaction under reflux conditions of anhydrous ammonia with certain perfluorinated alkyl or alkylether dinitriles; (2) forming a linear polytriazine by cyclizing the imidoylamidine linkages by reaction with certain perfluorinated alkyl or alkylether acid anhydrides or halides; (3) extending the linear polytriazine chain by further refluxing in anhydrous ammonia; and (4) heating to cyclize the new imidoylamidine linkages and thereby crosslink the polymer.Type: GrantFiled: April 9, 1979Date of Patent: December 30, 1980Inventors: Robert A. Administrator of the National Aeronautics and Space Administration, with respect to an invention of Frosch, Robert W. Rosser, Roger A. Korus

Patent number: 4234715Abstract: New perfluoroalkyl polytriazines containing pendent iododifluoromethyl groups are prepared by the reaction of perfluoroalkyl dinitriles with ammonia to form poly(imidoylamidines), followed by the cyclization of the imidoylamidine groups with, e.g. various mixtures of a perfluoroacyl fluoride with an .omega.-iodoperfluoroacyl fluoride. The polytriazines obtained can be cured by heat which causes crosslinking at the iododifluoromethyl groups by elimination of iodine and formation of carbon-to-carbon bonds.Type: GrantFiled: May 8, 1979Date of Patent: November 18, 1980Inventors: Robert A. Administrator of the National Aeronautics and Space Administration, with respect to an invention of Frosch, Robert W. Rosser, Theodore Psarras
