Abstract
A process for the synthesis of a diene copolymer comprising at least two blocks, at least one of the blocks being composed of a diene elastomer, characterized in that it comprises a stage of 1,3-dipolar reaction of two polymers defined as being: This process of synthesis can be adjusted, whatever the nature of the monomers necessary to form each of the blocks of the copolymer. Each block can be synthesized with an appropriate chemistry, independently of the other block.
