TREATMENTS FOR INHIBITING VINYL AROMATIC MONOMER POLYMERIZATION |
摘要 |
Compositions and methods for inhibiting vinyl aromatic monomer polymerization during processing are disclosed. The compositions are combinations of a dinitrosalicylic acid derivative and a hydroxylamine compound and are added to the monomer during processing. The preferred composition is 3,5-dinitrosalicylic acid or 3,5-dinitrosalicylic methyl ester and bis-(hydroxypropyl)hydroxylamine in a weight ratio ranging from 1:9 to 9:1.
