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.

Abstract: Blends of elastomer composites with unfilled or less highly filled elastomer reduces hysteresis without compromising reinforcement. Hysteresis may also be reduced by adjusting the compounding method.

Abstract: A method of producing an elastomer composite. The method includes A) combining a first fluid comprising elastomer latex with a second fluid comprising particulate filler; B) causing the elastomer latex to coagulate, thereby forming masterbatch crumb; C) bringing the masterbatch crumb to a water content of about 1 weight percent to about 20 weight percent, thereby forming a de-watered coagulum; D) removing water from the de-watered coagulum by subjecting the dewatered coagulum to mechanical energy, thereby causing the dewatered coagulum to heat as a result of friction, while allowing the dewatered coagulum to achieve a temperature of about 130° C. to about 190° C., wherein water content is reduced to about 0.5% to about 3% and wherein substantially all of the decrease in water content is accomplished by evaporation, thereby producing a masticated masterbatch; and E) subjecting the masticated masterbatch to at least an additional 0.3 MJ/kg of mechanical energy while further reducing the water content.
