Abstract
The invention relates to a modified diene elastomer comprising predominantly the entity functionalized in the middle of the chain by a silanol group, the silicon atom of which bonds the two pieces of the chain, the chain ends of the modified diene elastomer being functionalized to at least 70 mol %, with respect to the number of moles of chain end, by an amine functional group.
