The present invention relates to a method for preparing a macromolecular composition comprising phenylglyoxaldehyde-derivatives. The invention also relates to the macromolecular compositions per se, and to methods of using the macromolecular compositions. The macromolecular compositions are useful for undergoing subsequent reactions with small molecules, for instance to remove such small molecules from a solution.

The invention is directed to a method for attaching nanomaterials containing hexagonal lattices to polymer surfaces. For example, carbon nanotubes (CNTs) can be attached to polycarbonate, polyethylene, or epoxy surfaces by amination of the polymer surface, functionalization of the surfaces of CNTs with ester groups, and reacting the aminated surface of the polymer with the ester groups of the functionalized surfaces of the CNTs in an organic solvent to chemically bind the CNTs to the polymer surface.

Polar silane linkers are provided that attach to resins to form silane-functionalized resins. The functionalized resins can be bound to hydroxyl groups on the surface of silica particles to improve the dispersibility of the silica particles in rubber mixtures. Further disclosed are synthetic routes to provide the silane-functionalized resins, as well as various uses and end products that benefit from the unexpected properties of the silane-functionalized resins. Silane-functionalized resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the silane-functionalized resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, and wet braking performance.

The disclosure relates to the field of metal ion capture, more particularly of selective capture of nickel Ni(II) ions, by a polymeric compound based on a polymer selected from styrenic polymers and chloropolymers. In the polymeric compound, at least one portion of the monomer units of the polymer is functionalised by the ligand, the ligand including at least one chemical group selected from the glyoxime groups.

The glyoxime groups have a strong affinity for the Ni(II) ions, as well as an excellent selectivity vis-à-vis metal ions of chemical properties similar to Ni(II) ions. This ligand thus allows a selective complexation of the Ni(II) ions by the polymeric compound, including in solutions of low concentrations of Ni(II) ions.

The polymeric compound according to at least one embodiment of the disclosure is particularly intended for capturing the Ni(II) ions during the electrogalvanising methods as well as for recycling material comprising nickel.
