    Abstract

    Currently available antiozonants such as N-isopropyl-N′-phenyl-p-phenylene diamine (IPPD) and N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylene diamine (6PPD) migrate either during vulcanization or during service, thus affecting ageing protection and fatigue resistance. A slow migrating antiozonant and also a relevant test protocol for screening potential candidates providing slow diffusion antiozonant protection was developed. In this paper a comparison has been made with regard to migration of antidegradants such as 6PPD, IPPD and development products in typical sidewall compounds using a recently developed test protocol. The combination of 6PPD and the development product provide longer lasting and better appearance of tire black sidewalls. Physical and dynamic properties are better retained in presence of the newly developed antidegradant. A good migration correlation was found between outdoor ageing and the dynamic ageing test method.
