ABSTRACT:
A cleaning method for removing scales, etc., deposited on the interior of a polymerization reactor which has been used in emulsion or suspension polymerization. This method uses a chemical cleanser comprising a soap builder an, alkali agent, an aqueous solution or dispersion of a surfactant, and an organic solvent and/or polymerizable monomer. This system may further contain a plastic packing such as tellerettes. By this method, scales deposited on the interior of a polymerization reactor, particularly, scales deposited on the inside surface, agitator, and baffle-plates of the reactor, are compeltely removed.
