Abstract
A reduced oil rubber composition includes (a) a silica filler, (b) a N-substituted polyalkylene succinimide derivative, and (c) a rubber matrix. In certain embodiments, the composition may comprise a reduced amount of oil, especially a reduced amount of aromatic oil or even no aromatic oil. Rubber articles manufactured from such composition, such as tires and power belts, have improved properties such as reduced rolling resistance, improved wet/snow traction and winter softness, improved dynamic stiffness, improved tensile strength, easy handling, and/or compatibility with higher environmental standard, among others.
