Process for the polimerizacao continues to polymers of diorganopoli siloxane terminated in silanol

摘要

A process for the continuous manufacture of diorganopolysiloxane polymers. The polymerization reaction takes place in a static mixer wherein dimethyl cyclic polysiloxane monomers are treated with a potassium silanolate catalyst. Efficiency of the static mixer is maintained by the early introduction of water chain-stopper which effectively provides for a plug flow condition within the polymerizer section. Preparation of other polysiloxane fluids utilizing triorganosiloxy chainstopper is also disclosed.
