Abstract
Treatment of 1-(hydroxydimethylsiloxy)pentamethylcyclotrisiloxane (II), a latent A2A‘B monomer, with a phosphazene P4-t-Bu superbase followed by quenching with vinyldimethylchlorosilane/triethylamine leads to a hyperbranched polysiloxane (III). The microstructure and properties of III are compared to those of linear analogues obtained by cationic or living anionic polymerization of 1-(vinyldimethylsiloxydimethylsiloxy)pentamethylcyclotrisiloxane (I).
