Rubber compositions including metal phosphate esters |
| 摘要 |
A composition includes a diene rubber and a metal phosphate ester of the formula:;
M being a metal with an oxidation state of +3 or +4, and R1 and R2 are independently selected from any organic moiety including hydrogen, except R1 and R2 cannot both be hydrogen. In addition, a method of making a rubber composition includes combining a solvent and a phosphate ester and mixing these to foam a solution. A source of metal ions is then added to the solution. The metal in the source of metal ions is selected from the group consisting of metals with an oxidation state of +3 or +4. The product is then is combined with a diene rubber composition to form a useful article, such as the tread of a tire. |

1. A composition comprising:
a diene rubber, a metal phosphate ester of the formula wherein M is a metal with an oxidation state of +3 or +4, R1 and R2 are independently selected from any organic moiety or hydrogen, except R1 and R2 cannot both be hydrogen, and n is the oxidation state of M. |
