    • A halide salt of a 1-(hydroxyiminomethyl-1-pyridino)-3-(halomethyl)-2-oxapropane is prepared by adding a pyridinealdoxime to a bis-halomethylether in such a manner that the bis-halomethylether is maintained in excess throughout the addition. This procedure produces the halide salt of a 1-(hydroxyiminomethyl-1-pyridino)-3-(halomethyl) -2-oxapropanein high yield and purity, which facilitates its use as an intermediate in the manufacture of an asymmetrically substituted 1,3-di (1-pyridino)-2-oxapropane, a class of compounds that are generally useful antidotes to various toxic agents. A prominent member of the class is the dimethylsulfonate salt of 1-(2-hydroxyiminomethyl-1-pyridino)-3 -(4-carbamoyl-1-pyridino)-2-oxapropane. The use of mercaptoalkyl-functionalized polymers is disclosed as a preferred metal ion scavenger for a final purification step in the manufacture of these compounds.

    • This application is directed to novel fluorinated polymers and prepolymers derived from mono-substituted oxetane monomers having fluorinated alkoxymethylene side-chains and the method of making these compositions. The mono-substituted fluorinated oxetane monomers having fluorinated alkoxymethylene side-chains are prepared in high yield by the reaction of a fluorinated alkoxides with either 3-halomethyl-3-methyloxetane premonomers or aryl sulfonate derivative of 3-hydroxymethyl-3-methyloxetane premonomers. Preparation of a mono-substituted 3-bromomethyl-3-methyloxetane premonomer via a simple, high yield process amenable to commercial scaleup is also disclosed. The fluorinated oxetane monomers of this invention can be readily homo/co-polymerized in the presence of a Lewis acid and polyhydroxy compounds to obtain hydroxy-terminated polyether prepolymers having fluorinated alkoxymethylene side chains. Additionally, the fluorinated oxetane monomers can be copolymerized with non-fluorinated monomers such as tetrahydrofuran to give polyether prepolymers with improved hydrocarbon compatibility. These prepolymers are polydisperse and exhibit number average molecular weights from 5,000 to about 50,000. These prepolymers are amorphous oils with primary hydroxy end-groups and thus function efficiently as the soft block for the synthesis of a variety of thermoset/thermoplastic elastomers and plastics having the characteristics of very low surface energy, high hydrophobicity, low glasss transition temperature and low coefficient of friction. The polyurethanes derived from the prepolymers of this invention are elastomeric and, in addition to the above characteristics, exhibit high moisture resistance, high tear strength and excellent adhesion to a variety of substrates.

    • The present invention provides fluorinated diamines and polymers formed therefrom, such as polyureas, polyurethane ureas, polyamides, polyimides, etc. The fluorinated diamines of the present invention are highly nucleophilic and are structured to provide polymeric materials having optimum surface properties. In the fluorinated diamines of the present invention, the end groups are primary amino groups which are substantially removed from the perfluoroalkyl groups. Moreover, the fluorine is present in the side chains which allows the fluorocarbon segments to migrate to the polymer/air interface, thereby providing polymer surfaces with high fluorine concentrations. As such, the polymers formed from the fluorinated diamines of the present invention have a variety of commercial applications as stain and oil resistant coatings, fouling release coatings, encapsulants for electrical devices, curing agents for epoxies, etc.

    • The present invention provides an improved method of carrying out cationic polymerization of cyclic ether monomers substituted with high-energy, electron-withdrawing pendant groups (e.g., BAMO and NMMO). Such cyclic ether monomers are polymerized with an initiator precursor (i.e., an alcohol) and boron trifluoride tetrahydrofuranate (BF.sub.3 .cndot.THF). It has been discovered that when boron trifluoride tetrahydrofuranate is used as a catalyst in the cationic polymerization of cyclic ether monomers substituted with high-energy, electron-withdrawing pendant groups (e.g., BAMO and NMMO), polymers are produced that have improved functionality and low poly-dispersity. The polymers formed using the method of the present invention are useful for forming cross-linked elastomers which, in turn, are useful for forming elastomeric binders for high-energy compositions, such as propellants, explosives, gasifiers or the like.
