Embodiment Construction

[0017] The carbon black of the present invention is characterized as having an iodine value of from about 50 to about 112 mg / g, preferably from about 73 to about 104 mg / g, more preferably from about 75 to about 99 mg / g, and having a primary particle size of no greater than 25 nm according to ASTM Test Procedure D3849- 89 measurements.

[0018] Certain carbon blacks of the present invention can be further characterized as having a CDBP (dibutyl absorption value of comminuted carbon black) of less than or equal to 102 cubic centimeters DBP per 100 grams of carbon black (cc / 100 g), as measured according to ASTM Test Procedure D3493-86.

[0019] Examples of carbon black include an iodine value of 65-95 mg / g and a primary particle diameter of 20 nm or less. The carbon black may have an iodine value of 73-94 mg / g, and a primary particle size less than or equal to 19 nm.

[0020] The carbon black may have an iodine value of 85-93 mg / g, and a primary particle size less than or equal ...

Abstract

Carbon blacks are described having an I2 No. of 50-112 mg / g, and a primary particle size of not greater than 25 nm and are particularly well suited for use in the production of polymer compositions. Also described are polymer compositions incorporating the carbon blacks.

Description

technical field [0001] The present invention relates to a new class of useful carbon blacks suitable for a variety of applications, particularly for use in polymeric compositions, natural rubber, synthetic rubber, elastomers and / or blends or mixtures thereof. The present invention also relates to novel and useful polymer compositions (polymers, natural rubbers, synthetic rubbers, elastomers and / or blends or mixtures thereof) comprising the carbon black. Background of the invention [0002] Carbon black is typically produced in a furnace-type reactor by thermally decomposing a hydrocarbon feedstock with hot combustion gases to produce a combustion product comprising particulate carbon black. [0003] Carbon black can be used as a pigment, filler and / or reinforcing agent in polymer compositions. [0004] Carbon black can be used to impart electrical conductivity to the polymer composition and to protect the polymer composition from ultraviolet (UV) degradation. For example, ...
