Estimating the term…
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 a polymer to form a polymeric product.
A polymeric product comprising a polymer and a modified carbon product dispersed therein, wherein said modified carbon product comprises a carbon product having attached the formula:
A method for improving the dispersion of a carbon product in a polymeric product comprising dispersing a modified carbon product in a polymer, wherein said modified carbon product comprises a carbon product having attached at least one polymeric group which is compatible with said polymer, wherein said modified carbon product comprises at least one aromatic group directly attached to a carbon product and at least one polymeric group attached to said aromatic group, and wherein said polymeric group is a polyolefin group, a polystyrenic group, a polyacrylate group, a polyamide group, a polyester group, or mixtures thereof.
A method for increasing the dispersion of a carbon product in a polymer product comprising dispersing a modified carbon product in a polymer, wherein said modified carbon product comprises a carbon product having attached a group having the formula —Ar—CO2R or —CnH2nCO2—R, where R is a polymeric group, Ar is an aromatic group, and wherein said polymeric group is a polyolefin group, a polystyrenic group, a polyacrylate group, a polyamide group, a polyester group, or mixtures thereof.
A polymeric product comprising at least one polymer and at least one modified carbon product dispersed therein, wherein said modified carbon product comprises at least one aromatic group directly attached to a carbon product and at least one polymeric group attached to said aromatic group, and wherein said polymeric group is a polyolefin group, a polystyrenic group, a polyacrylate group, a polyester group, or mixtures thereof.
