MULTIMODAL POLYMERS THROUGH CONTROLLED FREE RADICAL POLYMERIZATION IN THE PRESENCE OF ALCOXYAMINES

摘要

the invention relates to a process for preparing a polymer by free radical polymerization of a multimodal monomer in the presence of at least one of the sequence of alcoxyamines made several(e) (see formula (i) in which r is a monovalent radical having a molecular weight greater than 15, is the heart of the alcoxyamine, n is an integer not nullthe alcoxyamines with different n values.
