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 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. 本发明涉及用于合成具有高含量的磷官能团的新型二烯聚合物的方法，所述方法根据如下步骤将带有链端硫醇官能团的聚(磷)聚合物自由基接枝至二烯聚合物：a)伴随搅拌混合至少种溶液形式的二烯聚合物和带有链端硫醇官能团的至少种溶液形式的聚(磷)聚合物；b)将前述步骤中获得的均质反应混合物加热至接枝反应温度，和c)在步骤a)或b)的过程中或者在达到接枝反应温度时加入自由基引发剂。
