Method for producing ABA-triblock copolymers with a bimodal B-block

摘要

The invention relates to a controlled polymerization method for producing ABA-triblock copolymers on the basis of (meth)acrylate with A-blocks which have a narrow, monomodal molecular weight distribution and a B-block which has a bimodal molecular weight distribution, and to the use thereof as binders in glues and sealing materials.
