A process is disclosed for the preparation of vanadium trineodecanoate to used as one component of a promoter used in conjunction with a catalyst to cure a polyester resin. Vanadium pentoxide is reacted or reduced in an acidic solution. The resultant mixture is heated and thereupon neodecanoic acid triethyl phosphate, paraformaldehyde and xylene are added. This solution is azeotropically distilled. Vanadium trineodecanoate is recovered in a xylene phase.

Synthesis of hydrocarbon soluble vanadium catalyst

Hydroxy terminated polybutadiene is reacted with naphthyl-potassium and 1omo-2,4-pentadiene in successive steps to form a bis(1,3-pentadienyl ether) derivative. Then the bismaleimide of dimer diamine is added to the polybutadiene derivative whereby a room temperature cure to an elastomer is achieved.

A solid propellant formulation and method of preparation which has enhanced urning rate characteristics and improved mechanical properties. The formulation comprises a binder, a fuel and an inorganic oxidizer consisting of ammonium perchlorate whiskers which are oriented along the direction of shear.

Hydroxy terminated polybutadiene is reacted with naphtyl-potassium and 1-mo-2,4-pentadiene in successive steps to form a bis(1,3-pentadienyl ether) derivative. Then the bismaleimide of dimer diamine is added to the polybutadiene derivative whereby a room temperature cure to an elastomer is achieved.

A stripline board material of hollow glass microspheres chemically bonded to a coating material and physically held in a polymeric matrix, preferably homo- or co-polymers of ethylene, propylene and/or styrene. The coating material is a difunctional silane with one functional group bound to the glass and the other bound either to the matrix or to a copolymer of a structure similar to the structure of the matrix. In the latter case, the sphere-silane-copolymer forms an intimate mixture with the matrix.

Composite for improved stripline board material

A method for manufacturing large, nonplanar, transparent, gelatin-coated ymer sheets is disclosed. These sheets when sensitized, exposed, and developed can record and display holograms. A poly(methyl methacrylate) sheet is coated with nitrocellulose, the nitrocellulose is denitrated, and a gelatin solution is applied, then hardened. The sheet with its gelatin film is then thermally formed to any desired three-dimensional configuration.

Compositions of matter comprising a mixture of a jet fuel and an aluminum di-acid soap of a saturated carboxylic acid having from 8 to 20 carbon atoms are disclosed. The compositions of matter are useful as fuels for jet aircraft.
