    Abstract: LIQUID NITROSO RUBBER PREPOLYMERS ARE DISCLOSED HAVING A MOLECULAR WEIGHT BELOW ABOUT 20,000 AND THE GENERAL FORMUAL:

    Z-(-CF2-CF2-N(=O)(-CF3))M- -(CF2-CF2-N(=O)(-(CF2)P-COO-R)-

    )N-CF2-CF2-Z

    WHEREIN R IS SELECTED FROM HYDROGEN AND ALKYL GROUPS OF 1 TO 6 CARBON ATOMS, Z IS SELECTED FROM CHLORINE, BROMINE, IODINE AND -NO2, P IS 2 TO 6 AND THE RATIO M:N IS FROM 1:1 TO 50:1. THE LIQUID PREPOLYMERS MAY BE PREPARED BY COPOLYMERIZING PERFLUORONITROSOMETHANE, TETRAFLUOROETHYLENE AND A NITROSOPERFLUORO ACID OR ESTER IN THE PRESENCE OF A TERMINATOR WHICH MAY BE CHLORINE, BROMINE, IODINE OR NITORGEN DIOXIDE. THE POLYMERS CAN BE CURED WITH SUCH CURING AGENTS AS EPOXIDES, METAL OXIDES AND CHROMIUM PERFLUOROACETATE TO PRODUCE RUBBERS HAVING GOOD PHYSICAL PROPERTIES AND CHEMICAL RESISTANCE.

    Abstract: Nitroso polymers are provided which are produced by reacting certain nitroso ether monomers. These polymers in turn yield novel polymers by converting, partially or substantially fully, pendant groups in the obtained polymer. The precursor polymers as well as the converted polymers are highly oxidation resistant. Elastomers can be produced directly from the precursor as well as the desired polymer. Liquid as well as solid polymers are provided. These polymers are represented by the following general formulas

    The liquid polymers are appropriately chain-terminated with a chain terminator such as chlorine.

    Abstract: A LINEAR NITROSO POLYMER HAS BEEN PROVIDED BY POLYMERIZING MONOMERS WITH PENDANT, CNVERTIBLE MOIETIES WHICH ARE CROSSLINKABLE. THESE MONOMERS WITH THE CROSSLINKABLE, PENDANT GROUPS CANNOT BE INTRODUCED INTO THE POLYMER DIRECTLY; HENCE, THE CONTRIBUTION RESIDES IN THE ROUTE OF INCORPORATING PRECURSOR MOIETIES IN THE POLYMER BACKBONE AND THEN OBTAINING A POLYMER. THE POLYMERS WITH THE CONVERTIBLE, PENDANT GROUPS ARE DERIVED FROM RECURRING UNITS AS REPRESENTED BY THE GENERAL FORMULAE:

    -(CF2-CF2-N(-CF3)-O)M-(CF2-CF2-N(-CF2-CO-Z)-O)N-

    OR T-(CF2-CF2-N(-CF3)-O)M-(CF2-CF2-N(-CF2-C-O-Z)-O)N-CF2-

    CF2-T

    WHEREIN Z IA A-O-(LOWER ALKYL) GROUP OF 1 TO 7 CARBON ATOMS OR CHLORINE; AND T IS A HALOGEN, A PERHALOALKYL, -NO, OR-NO2, AND THE RATIO M:N IS FROM 0:1 TO 50:1. LIQUID AND SOLID POLYMERS ARE PROVIDED AS WELL AS ELASTOMERS DERIVED THEREFROM. A METHOD FOR PREPARING AND CONVERTING THESE MONOMERS HAS ALSO BEEN DISCLOSED.

    Abstract: The invention comprises carborane polyols of the formula wherein R1 and R2 are hydrocarbon groups and preferably lower alkyl groups having from 1 to 4 carbon atoms, or hydrogen, R3 is such a hydrocarbon group, or hydrogen, or a polyol group of the formula wherein R4 and R5 are hydrocarbon groups, preferably lower alkyl groups having from 1 to 4 carbon atoms, or hydrogen, and #q is C2H10B10. The compounds may be made by reacting an epoxy alkenylcarborane of the formula with water in the presence of an acid catalyst, such as sulphuric acid, or Lewis acids such as boron trifluoride. Diepoxy - dialkenyl - carboranes can similarly be converted to carborane polyols. The epoxyalkenylcarboranes may be made by reacting an alkenyl carborane in an inert solvent medium with hydrogen peroxide and trifluoroacetic anhydride.

    Abstract: Boron containing polymers are prepared by reacting an organoboron diol of the formula HOR1OR2OH or (HOR1OR2)O, wherein O is a divalent carboranyl radical -CB10H10C- and R1 and R2 are divalent aliphatic groups together comprising at least 3 carbon atoms in a linear chain with the carboranyl group with an aldehyde such that the copolymer has at least six atoms between two adjacent carboranyl groups of each three successive carboranyl groups. Suitable carboranyl radical containing diols are bis - (2 - hydroxyethyl - 1 - carboranylmethyl)-ether. 1 - Hydroxyethyl - 2 - hydroxypropyl-carborane and bis - (hydroxyethyl) - carborane. Preferred aldehydes are formaldehyde and its donors, acetaldehyde and crotonaldehyde. The reaction may be catalysed by an acidic catalyst such as para toluene sulphonic acid. Cross-linking of the polymers may be effected by use of di- or tri-isocyanates.
