Synergistic combination to inhibit polymerization |
| abstract |
A synergistic polymerization inhibitor composition having a copper salt and a manganese salt; a copper salt or a manganese salt and a cationic polymer; or a phenothiazine and a manganese salt. A method for inhibiting the polymerization of unsaturated polymerizable monomers, which provides a step of adding a synergistic polymerization inhibitor composition to a methacrylic acid production system or its components, wherein the composition is a copper salt and a manganese salt. A method having a copper salt or a manganese salt and a cationic polymer; or a phenothiazine and a manganese salt. |
