Abstract
The influence of trimethylsilanol (TMS) on the polymerization of hexamethylcyclotrisiloxane (D 3) under the action of sodium trimethylsilanolate (TMSN) has been studied. It has been shown that as the molar ratio [TMS] 0 : [TMSN] 0 = α increases, the activity of the TMSN, the activation energy and the pre-exponential factor of the Arrhenius equation are all increased. The influence of the TMS is due to breakdown of associates of TMSN and to the formation of associates of TMSN with TMS. TMS participates directly in the reaction due to interaction with D 3 and its polymerization products.
