| 摘要 |
The present disclosure provides a process for preparing silicone emulsions via suspension polymerization techniques that are faster and/or provide higher molecular weight organopolysiloxanes than conventional techniques. The process involves combining a) an emulsifier, b) a silanol functional organopolysiloxane, c) a polymerization catalyst, and water to form a mixture, shearing the mixture to form an emulsion having a dispersed phase of the organopolysiloxane, reacting the emulsion in a closed system having a pressure greater than 1 MPa to polymerize the organopolysiloxane. |
