Abstract
Various modified carbon products are disclosed which can form a part of a polymeric product containing the modified carbon product and a polymer. One type of modified carbon product disclosed is a carbon product having attached at least one organic group, monomeric group, or polymeric group. Another type of modified carbon product disclosed is a carbon product having attached a group having the formula: —Ar—CO2—R or —CnH2nCO2—R where R is an organic group, monomeric group, or a polymeric group. The third type of modified carbon product contains a) a carbon product having attached at least one organic group directly attached to the carbon product, b) at least one ionic group, ionizable group, or a mixture thereof attached to the organic group, and c) at least one counter-ionic group or counter-ionizable group with at least one organic group, monomeric group, or polymeric group, or mixture thereof, where the counter-ionic or counter-ionizable group is attached to the ionic and/or ionizable group. A method of improving the dispersion of carbon products in polymers is also disclosed which involves dispersing the modified carbon products described above in …
