摘要： The invention relates to a method for controlling the structure of a block copolymer by selective ring-opening copolymerisation of cyclic carbonate and lactone monomers in the presence of a catalyst based on methanesulfonic acid, said method comprising a sequence of steps carried out strictly in the following order: a) dissolving the cyclic carbonate monomer in a non-chlorinated aromatic solvent, b) adding a bifunctional initiator selected from diols or water to the monomer solution, c) adding methanesulfonic acid (MSA) as a catalyst of the polymerisation reaction, d) once all of the cyclic carbonate has been consumed, producing a telechelic polycarbonate that can act as a macroinitiator of polymerisation of the lactone, and e) adding the lactone to the reactive medium for the selective production of a block copolymer.
