    摘要: Ionomers comprising higher alkyl ammonium or quaternary polyammonium salts of polyacids, particularly sulfonic acids, having anionic groups covalently bonded to carbon atoms comprising a backbone chain of a polymer, or to acyclic, alicyclic or aromatic radicals which are pendant to the backbone chain of the polymer, are novel compositions of matter. These ionomers vary in properties from water-soluble polyelectrolytes useful as thickening agents to thermoplastic elastomers which can be extruded, injection molded, vacuum formed, etc. at elevated temperatures. The elastomers are useful as specialty and general purpose rubbers.

    摘要: Episulfides are reacted with mono, di or trithiols in the presence of tertiary aliphatic amines or tertiary aliphatic phosphines, to form corresponding thioether thiols by a highly selective anionic mechanism. Increasing episulfide-thiol ratios result in polythioether thiols of increasing molecular weights. Using two or more episulfides, block copolymers can be prepared. The reactive terminal thiol functionality and the segmented crystalline and amorphous block structure of the new polymers makes them particularly useful for castable rubber applications.

    摘要: N,N-dichloro-N-acyl compounds, such as N,N-dichlorocarbamates, sulfonamides and amidosulfonamides selectively react with conjugated dienes to yield the corresponding 1,4-adducts, i.e. N-chloro-N-chlorocrotyl compounds. The N-chloro group of these adducts can be selectively reduced by aqueous sodium sulfite. Both the original and the reduced adducts are novel compositions useful as biologically active compounds and vulcanizing agents. The N-chlorocrotyl sulfonamides and their N-chloro derivatives are particularly claimed compositions.
