    摘要: 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.

    摘要: This invention relates to novel multifunctional oxetanes, i.e., compounds having multiple oxetane groups, which are useful as initiators in the preparation of star polymers and polymer cascades containing energetic groups. In addition, this invention relates to a process for the preparation of star polymers and polymer cascades, whereby novel multifunctional oxetanes act as initiators in the formation of theses polymers. The reaction of these initiators with various propagating, high-energy oxetanes, such as 3,3-bis-(azidomethyl)oxetane (BAMO) and 3-nitratomethyl-3-methyloxetane (NMMO), gives star polymers with varying molecular weights and functionalities. The star polymers and polymer cascades of the present invention are useful as binders in high-energy formulations.

    摘要: 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.
