Abstract
Disclosed is a continuous process for producing silicone copolymers using a series of at least one stirred-tank reactor, the last of which reactors in said series has crude product stream feeding into at least one plug flow reactor, wherein this crude product stream is sufficiently homogeneous that this stream which undergoes further reaction in the plug flow reactor does not undergo phase separation.
