| abstract |
The invention relates to a rubber composition containing at least one diene elastomer and at least one reinforcing filler, said reinforcing filler comprising cellulose which is formed by nanocrystals and grafted by molecules of a coupling agent that can bond to the diene elastomer. The aforementioned molecules comprise at least one A function and one B function such that: A represents a functional group (A function) which can bond chemically to the cellulose and which comprises at least one heteroatom selected from among oxygen, phosphorous, halogens, nitrogen and sulphur; and B represents a functional group (B function) which can bond physically and/or chemically to the diene elastomer, said A and B functions being connected by an at least divalent X group. |
