PROCESS FOR THE ANIONIC POLYMERIZATION OF ACRYLIC MONOMERS AND VINYL COMONOMERS

摘要

A process for the polymerization of acrylic monomers and optionally of vinyl comonomers using (i) an initiator of formula (I): R-M (I) in which M denotes a metal selected from the group consisting of alkali metals and alkaline earth metals and R denotes a straight-chain or branched alkyl radical containing 2 to 6 carbon atoms or an aryl radical, and (ii) at least one non-nitrogenous macrocyclic complexing agent. The polymerization process is used to make products of acrylic polymers having a narrow distribution of molecular masses.
