    摘要: This invention pertains to olefins having a terminally disposed fluorocyclobutyl ring bearing a sulfonyl, sulfonic acid or sulfonate salt, a process for the production thereof, and polymers, especially ionomers, formed therefrom. The invention further pertains to ionically conductive compositions formed by the combination of a liquid and the ionomer of the invention, and electrochemical devices such as electrodes, sensors, and solid polymer electrolytes comprising those conductive compositions. The polymers of the invention arc useful in the formation of films and coatings with high chemical resistance and good physical properties. The ionomers of the invention are useful in electrochemical applications, particularly in lithium batteries. The polymeric compositions of the invention are useful for strong acid catalysis, such as Friedel-Crafts alkylation.

    摘要: Curable perfluoroelastomer compositions are disclosed that comprise ammonia and uncured perfluorinated elastomers having copolymerized units of nitrile-containing cure site monomers. Such compositions are curable at low temperatures. In addition, curable perfluoroelastomer compositions are disclosed wherein ammonia functions as a cure rate accelerator in the presence of other curing agents.
