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