Abstract
A process for preparing a rubber composition having improved properties, comprising mixing a rubber selected from the group consisting of natural and synthetic rubbers, with a carbon black product selected from the group consisting of carbon blacks characterized by having a factor of activity, which is the numerical product of the non-porous surface area, in square meters per gram of carbon black, by the carbon monoxide content in millimoles per gram of carbon black, of at least 62; an activity factor that represents the numerical product of the non-porous surface area, in square meters per gram of carbon black, by the content of hydrogen in millimoles per gram of carbon black, which is greater than 175; a value of the specific non-porous surface area ratio to the total specific surface area of the carbon black which is at least 0.8, and a dbp absorption index of at least 110 milliliters of dibutyl phthalate absorbed per 100 grams of carbon black in granules, said carbon black product being present in proportions of from about 10 to about 250 parts by weight per 100 parts by weight of rubber, and vulcanizing the mixture.
