      abstract     = {A diblock copolymer featuring a hydrophobic block with a
                      low glass transition temperature and a pH-responsive,
                      cationic block is synthesized and investigated with respect
                      to its self-assembly behavior in aqueous solution. The
                      synthesis of the poly(lauryl
                      methacrylate)-block-poly(2-(N,N-dimethylamino) ethyl
                      methacrylate) diblock copolymer PDMAEMA$_{60}$-b-PLMA$_{40}$
                      is carried out using reversible addition fragmentation chain
                      transfer (RAFT) polymerization. Its self-assembly in dilute
                      aqueous solution at pH 7 is investigated using various light
                      scattering methods. Micelles with a positive zeta potential
                      are identified. Synchrotron small-angle X-ray scattering
                      reveals changes in the inner structure of the micelles as a
                      function of temperature and at pH values above, below and
                      close to the pKa value of PDMAEMA (ca. 7.5). At all pH
                      values, cigar-shaped core–shell micelles are found. While
                      the micellar size and shape hardly change with temperature
                      at pH 5, temperature responsivity is observed at pH 7 and
                      10, resulting in, among others, a change of the core size.
                      These structural changes are facilitated by the softness of
                      the PLMA core. Such systems may be suitable for the
                      co-delivery of hydrophobic drugs and nucleic acids.},
