Abstract:
The invention relates to a controlled polymerization process for preparing (meth)acrylate-based AB diblock copolymers with a B block which has a narrow monomodal molecular weight distribution, and an A block which has a broad bimodal molecular weight distribution, and to the use thereof, for example, as a binder in adhesives or sealants.
