PROCESS FOR RADICAL GRAFTING OF A DIENE ELASTOMER |
摘要 |
The present invention relates to a process for radical grafting of a graft onto a diene elastomer, comprising the following steps: a. dissolving, with stirring, at least one diene elastomer and at least one thiol derivative as graft in a solvent comprising a mixture of at least one polar solvent and at least one nonpolar solvent, b. heating the homogeneous reaction mixture obtained in the previous step to the grafting reaction temperature, and c. once the grafting reaction temperature has been reached, adding the radical initiator in order to bring about the grafting of the graft onto the units of the elastomer comprising unsaturations. This radical grafting process makes it possible to achieve high grafting yields which can reach 100%. |
