Process for the preparation of pentablock copolymers functionalized with OH groups, characterized in that exactly two blocks are prepared, containing hydroxy-functionalized (meth) acrylates and monomers selected from the group of the non-hydroxy-functionalized (meth) acrylates or mixtures thereof and exactly three blocks, which contain some (meth) acrylates or mixtures thereof, which have no hydroxy function, and of which two blocks correspond in turn in their composition and the third block has a different composition, in the form of copolymers. pentablock |
