The Effect of Antitoxidants on the Mechanical Breakdown of Polyisobutylene Dissolved in Mineral Oil,
Abstract
The data presented shows that there is a real possibility of lowering the mechanical breakdown of polyisobutylene at the expense of antioxidant additives which are effective at the operating temperatures of the oil. The most effective stabilizer under the test conditions turned out to be 2-diethylaminomethyl-p-hydroxydiphenylamine, which lowers the breakdown of polyisobutylene by 1.7-1.8 times. Of the number of antioxidant additives of the type of screened phenols the additive, 2,2-methylene-bis-2,6-di-tert-butylphenol, turned out to be the best. (Author)
