    摘要: A reactor for chemical reactions, especially polymerization reactions, and in particular a reactor for emulsion, suspension, solution, bulk and/or precipitation polymerizations, which has a stirring mechanism, incoming and outgoing lines and a removable lid, and where both the stirring mechanism and incoming and outgoing lines are installed on the reactor floor. The novel reactor is quick and easy to open and clean and permits simple and rapid changeover of the installed stirring elements.
