Abstract
The present invention is directed to a process for the preparation of polyalkoxyaminies from monoalkoxyamine(s) of formula (I)and of at least one polyunsaturated compound of formula (II):and the preparation of polyfunctional living (co)polymers by polymerization by the radical route of one or more vinyl monomers in the presence of the polyalkoxyamines thus prepared.
