Abstract:
Antidegradant composition comprising a first compound of Formula I:
and a second antidegradant that is not the compound of Formula I; and rubber composition comprising the antidegradant composition. The rubber composition has good resistance to appearance discoloration while maintaining the mechanical and anti-aging properties, thus, are suitable for making the entire tire or as part of the rubber matrix.
and a second antidegradant that is not the compound of Formula I; and rubber composition comprising the antidegradant composition. The rubber composition has good resistance to appearance discoloration while maintaining the mechanical and anti-aging properties, thus, are suitable for making the entire tire or as part of the rubber matrix.
