## Abstract Methanol, in combination with a nonβionic phosphazene base, was used to initiate the polymerization of octamethylcyclotetrasiloxane. In bulk, an instantaneous and large increase in viscosity was observed upon addition of the initiator. In toluene solution, the equilibrium state was reac
## Abstract Hexamethylcyclotrisiloxane (D~3~), octamethylcyclotetrasiloxane (D~4~), and decamethylcyclopentasiloxane (D~5~) were equilibrated with potassium __tert__βbutoxide or triflic acid in bulk at 100βΒ°C to elaborate the ^1^H NMR and ^13^C NMR spectra, SEC elution curve, and MALDIβTOF (MT) mas
