Method for controlled polymerization via radicals, which uses a small amount of stable free radical.

摘要

The invention relates to a method of polymerization of at least one monomer radically polymerisable IN THE PRESENCE OF A STABLE FREE RADICAL AND A polymerization initiator, such as 100 moles of monomer. THE RADICAL STABLE molar amounts (SFR) AND PRIMER (AMO) are such that [(SFR) .F SFR] / [(AMO.F AMO] 0.15 YF SF R. (SFR) 0.2 MOL in which F FSR PRESENTS THE FUNCTIONALITY YF STABLE FREE RADICAL LOVE FUNCTIONALITY CHOKE REPRESENTS. The process of the invention has an advantageous kinetics, allows the realization of block copolymers or grafted and may miss extruder.
