摘要： A rubber composition is provided that includes a partially halogenated diene polymer that has a controllable microstructure, and no more than about 50% of the n repeat units are in blocks of three or more consecutive units. In embodiments, a reinforcing filler is also included in the rubber composition. In embodiment, the rubber composition is formed into a tire component. A method of making the composition is also provided.

摘要： The present disclosure is directed to rubber compositions containing a chemical additive capable of generating or enhancing strain-induced crystallization into the compositions, and tires containing the rubber compositions in one or more components such as sidewalls or treads. The chemical additive is at least one nucleating agent of formula (I) or formula (II). As well, certain embodiments relate to methods for achieving reduced wear or improved durability in a tire tread or tire sidewall by using the chemical additives.

摘要： A method of measuring wear rate in an actual rubber tire. A section of rubber is cut out of an actual tire below the surface of the tire. The cut out section is attached to the surface of a first wheel. An abrasive substance is attached to the surface of a second wheel. The two wheels are rotated for a predetermined time, in opposite directions, in contact with each other, at uneven rates resulting in some slippage between the surfaces of the two wheels. The wear rate of the rubber tire is measured based on the changes in the cut section over time, in much less time and using less resources than required by conventional wear measurement methods.
