The invention involves a process for the preparation of a multiblock copolymer, the process being carried out in the presence of a multifunctional initiator, said process comprising a combination of a cationic Ring Opening Polymerization (ROP) reaction catalyzed by at least one compound chosen from the group comprising Lewis acids, alkali metals and metal alkoxides, and a controlled (co)polymerization reaction, wherein the controlled (co)polymerization reaction is a Reversible Addition Fragmentation Chain Transfer Polymerization (RAFT), and that the multifunctional initiator is an inicta. |
