Abstract: The present invention relates to polymers and blends of polymers comprising anthracene moieties able to undergo a cycloaddition reaction under certain stimuli, thereby forming polymer adducts endowed with improved or additional properties with respect to those of the starting polymers.

Abstract: Described herein are poly(aryl ether) (“PAE”) adhesive compositions including at least one PAE chelating agent. The PAE chelating agent is a PAE polymer. In some embodiments, the PAE adhesive composition can optionally include one or more poly(aryl ether ketone) polymers distinct from the PAE chelating agent. The PAE adhesive composition can be incorporated into polymer-metal junctions to improve the strength thereof. In some such embodiments, the adhesive composition can be disposed between a portion of the plastic component and a portion of the metal component of the polymer-metal junction. In some embodiments, the PAE adhesive compositions can be used in conjunction with one or more adhesion promoters distinct from the PAE adhesive composition. In some embodiments, polymer-metal junctions including the PAE chelating agent can be desirably incorporated in mobile electronic device components.

Abstract: An anhydrous, proton-conductive medium comprises a poly(amic acid)-based polyimide and at least one phosphorus compound from the group consisting of phosphorus oxides and phosphoric acids. The precursor solution for the polyimide is a mixture of a phosphorus oxide and a poly(amic acid). A suitable phosphorus oxide has the formula P4O10. A process for forming an anhydrous, proton-conductive membrane comprises mixing a phosphorus oxide in a poly(amic acid) solution to form a mixture, dispensing the mixture upon a support structure, and substantially drying the mixture. The mixture may then be cured.

Abstract: A rechargeable lithium-air battery (10) comprises a non-aqueous, organic-solvent-based electrolyte (16) including a lithium salt and an additive containing an alkylene group, disposed between a spaced-apart pair of a lithium anode (12) and an air cathode (14). The alkylene additive may be alkylene carbonate, alkylene siloxane, or a combination of alkylene carbonate and alkylene siloxane. The alkylene carbonate may be vinylene carbonate, butylene carbonate, or a combination of vinylene carbonate and butylene carbonate. The alkylene siloxane may be a polymerizable silane. The polymerizable silane is triacetoxyvinylsilane.
