Abstract: Polymerization of anionically polymerizable monomers (A) is carried out in presence of a polymerization initiator containing a homoleptic lanthanoid compound (I) consisting of a divalent lanthanoid bonded to two identical ligands. The compounds (I) are new. Also new are polymers (B) of (A) obtained by the process. Polymerization of anionically polymerizable monomers (A) is carried out in presence of a polymerization initiator containing a homoleptic lanthanoid compound of formula (I). R-M-R (I) M : divalent lanthanoid; R : monovalent organic group (both R groups being the same). Independent claims are included for: (a) the compounds (I); (b) the use of (I) for the polymerization of (A); and (c) polymers (B) of (A) obtained by the above process.

Abstract: The invention relates to a polymerization initiator containing an alkaline-earth metal compound selected from the group: a) of the heteroleptic alkaline-earth metal compounds of formula (I) L - M - R or; b) of the cationic alkaline-earth metal complexes of formula (II) [D -} M - R] X , whereby M represents Ca, Sr or Ba; L represents a ligand which is inactive with regard to polymerization; R represents a ligand which is active with regard to polymerization; D represents a donor ligand and; X represents a non-coordinating anion. The invention also relates to methods for producing the polymerization initiators and to methods for carrying out anionic polymerization in the presence of the polymerization inhibitors.
