N-phenyl-1,2-dihydroquinolin-6-amines, nphenyl-1,2,3,4-tetrahydroquinolin-6-amines, and processes for preparing the same for use in rubber

Abstract

The present disclosure provides N-phenyl-1,2-dihydroquinolin-6-amines, N-phenyl-1,2,3,4-tetrahydroquinolin-6-amines, methods and processes for preparing N-phenyl-1,2-dihydroquinolin-6-amines, and methods and processes for preparing N-phenyl-1,2,3,4-tetrahydroquinolin-6-amines having antidegradant, e.g., antiozonant, antioxidant and / or antifatigue, properties. These compounds are useful additives for vulcanized rubber articles.
