Initiation system comprising a heterocyclic ligand for the (co) monomers anionic polymerization of (meth) acrylic and polymerization process that uses it.

摘要

The invention relates to a priming system comprising at least one primer, with the exception of amides alkaline, and at least one metal alcoholate ALCALINO OF FORMULA ROM, in which M is an alkali metal, R represents a group Q IN WHICH IS A 5- or 6-membered substituted or Y with 1 or 2 oxygen atoms as hetero atoms; R1 and R2 represent an alkylene group linear or branched C 1 -C 4 EQUALS YM 0, 1, 2 or 3. APPLICATION FOR PREPARING (CO) POLYMERS (meth) acrylic and, optionally, unsaturated monomers O ethylenic unsaturated monomers copolymerizable with (meth) acrylic.
