标题 :Method for the synthesis of thermoplastic elastomers in non-halogenated solvents
发明人：SANDERSON ANDREW J; EDWARDS WAYNE
权利人:CORDANT TECH INC; SANDERSON ANDREW J; EDWARDS WAYNE
摘要:A method of preparing a thermoplastic elastomer having A blocks which are crystalline at temperatures below about 75 °C and B blocks which are amorphous at temperatures above about -20 °C is disclosed. The A blocks are derived from oxetane derivatives and/or tetrahydrofuran derivatives. The B blocks are derived from oxetanes, tetrahydrofuran, oxiranes, and derivatives thereof. The A blocks and B blocks are dissolved into solution containing a non-halogenated solvent, preferably tetrahydrofuran. The dissolved A blocks and B blocks are dried of water by azeotropic distillation of the non-halogenated solvent. Next, the dried A blocks and the dried B-blocks are end-capped with a diisocyanate having one isocyanate moiety substantially more reactive with the terminal groups of the blocks than the other isocyanate moiety, whereby the more reactive isocyanate moiety is capable of reacting with the terminal groups of the blocks, leaving the less reactive isocyanate moiety free and unreacted. The end-capped A blocks and the end-capped B blocks are linked together with a linking compound having two isocyanate-reactive groups which are sufficiently unhindered to react with the free and unreacted isocyanate moieties of the end-capped polymers.

标题 :Synthesis of ABA triblock polymers and An B star polymers from cyclic ethers
发明人：WARDLE ROBERT B; HINSHAW JERALD C; EDWARDS WILLIAM W
权利人:THIOKOL CORP
摘要:ABA triblock and A n B star polymers are produced by sequential cationic polymerization of 4 and 5 member ring cyclic ethers to initially form a B block and subsequent cationic polymerization of 4 and 5 member ring cyclic ethers to form A blocks at the termini of the B block. The B block is grown from the hydroxyl groups of a polyol having two or more hydroxyl groups, resulting in a B block having terminal hydroxyl functionality of two or greater. In growing each of the B and A blocks, the acid catalyst is used at a molar ratio relative to hydroxyl groups of the polyol initiator of between about 0.05:1 and about 0.5:1.

标题:Synthesis of energetic thermoplastic elastomers containing oligomeric urethane linkages
发明人：SANDERSON ANDREW JOHN; EDWARDS WAYNE
权利人:ALLIANT TECHSYSTEMS INC
摘要:This thermoplastic elastomer is present in a substantially solid state suitable for use as a binder for a propellant, explosive, and/or gas generant of a supplemental restraint system. The thermoplastic elastomer is formed from a composition including A blocks which are crystalline at temperatures below about 75°C and B blocks which are amorphous at temperatures above about -20°C. The A blocks are derived from oxetane derivatives and/or tetrahydrofuran derivatives. The B blocks are derived from oxetanes, tetrahydrofuran, oxiranes, and derivatives thereof. The A and B blocks are end-capped with at least one diisocyanate and linked with at least one difunctional oligomer having two functional groups which are reactive with free and unreacted isocyanate moieties of the diisocyanate.

标题:Solvent-free process for the synthesis of energetic oxetane monomers
发明人：MALIK ASLAM A; MANSER GERALD E; CARSON ROLAND P; ARCHIBALD THOMAS G
权利人:AEROJET GENERAL CO
摘要:This invention relates to a process for the preparation of mono- and bis(azidomethyl)oxetanes. These compounds are prepared by combining a mono- or bis-X-oxetane (wherein X is, for example, a tosylate, mesylate, halogen, etc.) with an aqueous solution of a metallic azide and a phase transfer catalyst. Mono- and bis(azidomethyl)oxetanes can be polymerized to form homopolymers and copolymers with load bearing polyether backbones and highly energetic pendant groups. Such homopolymers and copolymers of the present invention are useful as energetic binders in high-energy formulations, such as propellants, explosives, and gasifiers.
