Abstract
A telechelic polymer of formula Z1-POLY-Z2 is provided. The term “POLY” denotes a polymer chain comprising units of a 1,3-diene, ethylene units and cyclic units, 1,2-cyclohexane units, Z1 and Z2 denoting a group containing a function, Z1 and Z2 being identical. The polymer has a macrostructure defined by a dispersity of less than 1.5 or by a number-average molar mass of greater than 10 000 g/mol.
