Abstract: In the production of high polymer polyorgano-siloxane convertible to silicone elastomers, oligomeric organo-siloxanes and catalyst are stirred in an upright container. The stirring is effected with a spiral stirrer disposed along the wall of the container, while the center of the container is free of conveyor means for free axial flow of the polymerizing material therethrough.
