摘要：

A kinetic study of the anionic polymerization of octamethylcyclotetrasiloxane (D-4) in aqueous emulsion has been carried out in the presence of ionic additives. The rate of polymerization of several cyclosiloxanes has been compared, leading to additional evidence for an interfacial mechanism of polymerization. The emulsion process has been applied to the cationic polymerization of D-4 and of tetramethylcyclotetrasiloxane (D-4(H)) initiated by dodecylbenzenesulfonic acid. Very efficient for the synthesis of linear polymethylhydrogenosiloxanes (PMHS), these conditions did not seem suitable for the polymerization of D-4. The extension of the process to other heterocyclic monomers is discussed through the anionic polymerization of phenylglycidylether.
