Abstract:
The invention concerns a method for the surface crosslinking of a polymer, in particle form, having one or a plurality of labile hydrogen functions, comprising a step of implementing a crosslinking agent comprising at least two functions likely to react with the labile hydrogen functions of the polymer, the crosslinking method being carried out at a temperature lower than the melting point of the polymer. The invention also concerns a powder particle and the uses of same.
