Novel functionalized polystyrenes having groups such as epichlorohydrin, epoxy, acetyl, C=C double bond, and carboxyl were synthesized by the reaction of polystyrene with epichlorohydrin, unsaturated hydrocarbons, and organic anhydrides in the presence of Lewis acid catalysts. The adhesion capability and corrosion resistance of the new synthesized functionalized polystyrenes to metals under various conditions were investigated. A very good relationship was observed between the quantity of functional groups bonded to the aromatic rings of the polystyrenes and the adhesion and corrosion resistance properties of the polyfunctionalized polystyrenes. It was also observed that the new polyfunctionalized polystyrenes obtained by chemical modification with maleic anhydride, acetic anhydride, isoprene, butadiene, and epichlorohydrin in the presence of cationic catalysts resulted in high adhesion and anti-corrosion properties.

A series of benzimidazolium ligand precursors were metalated with [RuCl2(p‐cymene)]2 to give ruthenium(II) N‐heterocyclic carbene complexes. All compounds were fully characterized by elemental analyses, 1H NMR, 13C NMR, and IR spectroscopy. The new benzimidazol‐2‐ylidene complexes have been found to be effective catalysis for the transfer hydrogenation of ketones by using 2‐propanol as the hydrogen source in the presence of KOH.
