Process for purifying styrene monomer feedstock prior to polymerization |
| abstract |
A process is disclosed which provides for the reduction of phenylacetylene levels in styrene monomer feedstreams, which process utilizes a normal styrene inhibitor additive, such as a hydroxylamine, injected into the styrene monomer feedstream immediately upstream of the phenylacetylene reduction reactor. |
