Method for the continuous production of organopolysiloxane gum solution

摘要

A highly productive method for the continuous production of homogeneous solutions of organopolysiloxane gums is carried out by mixing a solvent and an organopolysiloxane gum. It is characterized by using for mixing, a twin screw compounding extruder which is self-cleaning in which the extruder has at least 2 solvent feed ports downstream from the gum feed port and the internal pressure in the extruder is maintained at a value from 0.00981 to 0.981 MPa during the process.
