Method of surface crosslinking of a polymer, in the form of a particle, which has one or more functions with labile hydrogen, said polymer being chosen from polymers comprising one or more amide functions, polyurethanes, polyamines and a mixture of these polymers, comprising a step using a crosslinking agent comprising at least 2 functions capable of reacting with the hydrogen-labile functions of the polymer, the crosslinking procedure being carried out at a temperature below the melting point of the polymer. |
