Development of a new preparative procedure for hyperbranched polystyrene having Cl end groups (HPS–Cl) enables to prepare HPS–NR3+Cl−, for which the hydrophobicity/hydrophilicity is tunable by the R groups. The resulting ammonium salts behave as a good support of platinum nanoparticles, which is useful for catalytic biphasic hydrogenation of alkenes.
