Title:
POLYMERIZATION-TERMINATION DEVICE AND METHOD FOR CONTINUOUS PRODUCTION OF ORGANOPOLYSILOXANES
Document Type and Number:
WIPO Patent Application WO/2024/051671
Kind Code:
A1
Abstract:
The present invention relates to a polymerization-termination device and method for the continuous production of organopolysiloxanes. The device of the present invention comprises a reactor 1 and a reactor 2, which are directly connected to each other, wherein the polymerization reaction of a siloxane and devolatilization are performed in the reactor 1, and the termination of the polymerization reaction and deep devolatilization are performed in the reactor 2. The device of the present invention has a simple structure, improves the efficiency of polymerization and termination, and realizes controllable polymerization. The produced organopolysiloxane has a good quality, including a preparable product having a wide viscosity range, a small quantity of volatile components, a low content of impurities, a high transparency, a high thermal stability, etc.
