METHOD FOR PRODUCING DIENE POLYMERS BEARING PHOSPHORUS FUNCTIONAL GROUPS, PRODUCTS RESULTING FROM SAID METHOD AND COMPOSITION CONTAINING SAME

The invention relates to a method for the synthesis of a novel diene polymer with a high content of phosphorus functional groups by means of the radical grafting of a poly(phosphorus) polymer bearing a chain-end thiol functional group to a diene polymer according to the following steps: a) at least...

Zusammenfassung:The invention relates to a method for the synthesis of a novel diene polymer with a high content of phosphorus functional groups by means of the radical grafting of a poly(phosphorus) polymer bearing a chain-end thiol functional group to a diene polymer according to the following steps: a) at least one diene polymer in solution and at least one poly(phosphorus) polymer bearing a chain-end thiol functional group in solution are brought into contact under agitation; b) the homogenous reaction mixture obtained in the preceding step is heated to the temperature of the grafting reaction; and c) the radical initiator is added during step (a) or (b) or once the grafting reaction temperature has been reached.
