| 摘要 |
An anaerobic sealant composition capable of polymerizing upon exclusion of air comprises (1) a polyacrylic ester monomer, (2) an inorganic salt initiator which can be a persulfate or a perchlorate of ammonium, alkali metal or an alkaline earth metal, (3) a polymerization accelerator which can be a secondary or tertiary amine, a N,N-di(lower alkyl)amide of a monocarboxylic aliphatic acid, an organic carboximide of a polycarboxylic acid, or an organic sulfimide of a carboxylic acid, or mixtures of the foregoing (4) a N-nitrosoamine, and (5) a quinone-type polymerization inhibitor. The composition is prepared by compounding the aforementioned ingredients and suitably aging the resulting formulation.
