Abstract
Elastomeric compositions are described which have at least one functionalized elastomer and at least one modified filler which has adsorbed and/or attached chemical groups, such as a triazole and/or pyrazole thereon, or other modified fillers which are also described. Methods are further described to improve hysteresis and/or abrasion resistance in elastomeric compositions containing a functionalized elastomer using the modified fillers of the present invention.
