For the preparation of a multimodal polymer at least one monomer is subjected to free radical polymerization in the presence of several alkoxyamines comprising the sequence of formula: in which RL is a monovalent radical exhibiting a molar mass of greater than 15, A represents the core of the alkoxyamine and n is a non-zero integer, the alkoxyamines exhibiting different values of n.
