Patent number: 7294185Abstract: Processes for preparing a carbon black product having an organic group attached to the carbon black. In one process at least one diazonium salt reacts with a carbon black in the absence of an externally applied electric current sufficient to reduce the diazonium salt. In another process at least one diazonium salt reacts with a carbon black in a protic reaction medium. Carbon black products which may be prepared according to process of the invention are described as well as uses of such carbon black products in plastic compositions, rubber compositions, paper compositions, and textile compositions.Type: GrantFiled: March 22, 2004Date of Patent: November 13, 2007Assignee: Cabot CorporationInventors: James A.

Patent number: 6822781Abstract: A gyricon display containing modified particles is disclosed. The gyricon display has an arrangement of bichromal or polychromal elements which are disposed between a first and second electrode. One of the electrodes is substantially visually transparent. The display also has means for creating a potential difference between the two electrodes. Also, each bichromal element has two hemispheres, wherein one of the hemispheres has at least a surface containing at least one modified colored pigment having attached at least one organic group and the other hemisphere has at least a surface with a different color and different electrical property. The organic group preferably includes at least one ionic, ionizable group, or both. Each bichromal or polychromal element is enclosed within a shell wherein a liquid is present between the shell and the element so that the element is free to rotate in response. Methods of making the gyricon display are also disclosed.Type: GrantFiled: October 24, 2000Date of Patent: November 23, 2004Assignee: Cabot CorporationInventors: Robert M. Amici, Dennis M.

Patent number: 6534569Abstract: A variety of methods to prepare a polymer composition containing at least one polymer and at least one modified pigment are described. The methods, in part, involve introducing a slurry containing at least one modified pigment into an emulsion or solution polymer prior to dewatering. Other polymer systems can be used including aqueous based polymerizations and solvent-based polymerizations, which can include free radical polymerizations. Other methods involve the formation of a modified pigment in the presence of an emulsion or solution polymer and then recovering the polymer composition containing the modified pigment. Compositions containing at least one modified pigment and the emulsion or solution polymer are also described as well as uses for the polymer compositions of the present invention.Type: GrantFiled: January 24, 2001Date of Patent: March 18, 2003Assignee: Cabot CorporationInventors: Khaled Mahmud, James A.
