Abstract
The invention relates to a triblock diene elastomer, the central block of which is a polyether block having a number-average molecular weight ranging from 150 to 5000 g/mol and is connected via a silicon atom to each of the lateral blocks, and the chain ends of which are functionalized to at least 70 mol %, with respect to the number of moles of chain end, by an amine function.
