Abstract

A polymerisation reactor comprising a circulation loop with an inlet for raw material, driving means for circulating a reactor charge within the circulation loop, and an outlet connected to a discharge line for the discharge of polymer emulsion. The circulation loop includes a line section by-passing the circulation pump. The discharge line intersects the by-pass line. The outer end of the discharge line comprises an inlet for a cleaning pig while the other outer end leads to a collection tank. A shut-off valve is located between the cleaning pig inlet and the intersection of the discharge line and the loop. At the point of intersection the discharge line offsets the tube of the circulation loop at a distance greater than the radius of the discharge line.
