Process for preparing block copolymers by atom transfer radical polymerization (ATRP implemented sequentially in Aba triblock copolymer), comprising the block copolymer composition, pentabloco ACBCA or CABAC and use of block copolymers

摘要

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