## Abstract The anionic ringβopening polymerization of a model monomer of cyclodisilazanes 1, initiated with both organosodium and organolithium initiators, was investigated. Under specific conditions, this polymerization exhibits all the characteristics of a living process. Indeed, whatever the ex

Anionic polymerizations of 1,1-dimethylsilacyclobutane, 1,1-diethylsilacyclobutane and 1-methyl-1-phenylsilacyclobutane were investigated. Addition of 5 mol % of butyllithium to a solution of 1,1-dimethylsilacyclobutane in THF-hexane (1 : 1) at 048ΠC provided poly(1,1-dimethylsilabutane) in 99% yiel
Poly[1,1-bis(trimethylsilyloxy)-3,3,5,5-tetramethyltrisiloxane], the first linear polysiloxane in which each third silicon atom of the polymer backbone is a tetrafunctional SiO 2 (Q) unit, has been prepared by anionic ring-opening polymerization of 1,1-bis(trimethylsilyloxy)-3,3,5,5-tetramethylcyclo
Anionic ring-opening polymerization of a seven-membered cyclic carbonate, 1,3-dioxepan-2-one ( 1), was carried out to observe that the higher the polymerization temperature and lower the initial monomer concentration were, the lower the yield and molecular weight, and wider the molecular weight dist
