摘要：New classes of carbon blacks which may be broadly characterized as having an Iodine adsorption number (I2No.) of 50-112 milligrams/gram (mg/g) and a primary particle size measured in accordance with the procedures in ASTM Test Procedure D3849-89 (hereinafter denoted as "primary particle size") of less than or equal to 25 nanometers (nm). Certain of the carbon blacks of the present invention may be further characterized as having a CDBP (dibutyl absorption value of the crushed carbon black) of less than or equal to 102 cubic centimeters DBP per 100 grams of carbon black (cc/100g). The present invention provides carbon blacks having I2No. of 65-95 mg/g and a primary particle size of less than or equal to 20 nm. Also disclosed and claimed are carbon blacks having an I2No. of 100-112 mg/g and a primary particle size of less than or equal to 20 nm. The present invention further provides carbon blacks having an I2No. of 65-112 mg/g; a primary particle size of less than or equal to 20 nanometers (nm); and a CDBP (dibutyl absorption value of the crushed carbon black) of less than or equal to 102 cubic centimeters DBP per 100 grams of carbon black (cc/100g). In addition, carbon blacks having an I2No. of 50-70 milligrams/gram (mg/g) and a primary particle size of less than or equal to 25 nm, are disclosed and claimed. The present invention also provides carbon blacks having an I2No. of 50-85 mg/g; a primary particle size of less than or equal to 25 nm; and a CDBP of less than or equal to 96 cc/100g. The carbon blacks are particularly well suited for use in the production of polymer compositions. Also described and claimed are polymer compositions incorporating the new carbon blacks.
