    Abstract: The present invention provides a chromatographic stationary phase material various different types of chromatography. One example chromatographic stationary phase is represented by Formula 1 [X](W)a(Q)b(T)c (Formula 1). X can be a high purity chromatographic core composition. W can be absent and/or can include hydrogen and/or can include hydroxyl on the surface of X. Q can be bound directly to X and can include a first hydrophilic, polar, ionizable, and/or charged functional group that chromatographically interacts with the analyte. T can be bound directly to X and can include a second hydrophilic, polar, ionizable, and/or charged functional group that chromatographically interacts with the analyte. Additionally, Q and T can essentially eliminate chromatographic interaction between the analyte, and X and W, thereby minimizing retention variation over time (drift or change) under chromatographic conditions utilizing low water concentrations.

  • Patent number: 8008419
    Abstract: The invention provides novel siloxane monomers useful in a variety of adhesive applications. In one aspect, the siloxane compounds described herein can be used as Diels-Alder type curatives for bismaleimide or poly-maleimide monomers. The unsaturated resins shown here are attractive for use as maleimide curatives due to their poly-functionality. Each substituted styrenyl residue can react with two maleimide functional groups. Thus, an invention adhesive composition typically contains an excess of bismaleimide monomers.
