ABSTRACT:
In the polymerization under pressure of liquid olefin to polyolefin using a Ziegler type catalyst, the reaction mass, comprising a mixture of catalyst and polyolefin dissolved in liquid monomer, is mixed in a mixer with water to kill the catalyst and reaction after which the highly corrosive aqueous solution of Ziegler catalyst is separated from the monomer and dissolved polymer in a settling tank. The inner wall of the mixer and/or settling tank and/or any other part of the equipment coming into contact with the aqueous Zeigler catalyst solution is lined with an acid resistant brick lining having an intermediate membrane lining between it and the inner wall. A carbon filled furan resin is used as a mortar for the brick lining and the membrane is a fiber glass reinforced furan resin to which the brick lining is cemented by a carbon filled furan resin adhesive. The membrane is also cemented to the inner wall by a carbon filled furan resin adhesive.
