  • Publication number: 20170002148
    Abstract: Condensation of fluoro-substituted and silyl-substituted monomers provides polymers suitable for use, e.g., as engineering polymers. A monomer composition is condensed in the presence of a basic catalyst. The monomer composition contains a compound of formula F—X—F and a compound of formula (R1)3Si—Z—Si(R1)3, and forms an alternating X—Z polymer chain and a silyl fluoride byproduct. X has the formula -A(-R2-A)n-; each A is SO2, C(?O), or Het; R2 is an organic moiety; n is 0 or 1; Het is an aromatic nitrogen heterocycle; Z has the formula -L-R3-L-; each L is O, S, or N(R4); and each R3 is an organic moiety, and R4 comprises H or an organic moiety.

  • Patent number: 8101238
    Abstract: Adhesive polymers are formed when polyvalent azides and alkynes are assembled into crosslinked polymer networks by copper-catalyzed 1,3-dipolar cycloaddition. The condensation polymerization is efficiently promoted by Cu ions either leached from the metal surface or added to the monomer mixture, and strong interactions with metal surfaces are provided by the multiple triazole binding elements produced. The adhesive polymers may be formed either as adhesive polymer coatings or as adhesive polymer cement.
