AbstractThe initiation and propagation reactions in anionic non-equilibrium polymerization of octamethylcyclotetrasiloxane (D-4) initiated by silazyl-lithiums are investigated. It is found that: both the steric hindrance effect and the electronic effect of the substitutes on the Si atom Si influences the initiation activity of silazyl-lithiums; temperature effect on the propagation rate of D-4 increases strongly above 40degreesC; the molecular weight distribution of the prepared polysiloxanes widens with time.
