The last decades have witnessed great and (sometimes) unpredicted progress in the generation of sophisticated nanostructures from block copolymers in different microenvironments such as the solution state, in thin-films, or as bulk materials. Besides the wide variety of available building blocks, one intriguing feature of block copolymer self-assembly is that one single material can adopt different morphologies, depending on the surrounding conditions. Subtle changes in the environment, suitable additives, crystallization occurring, confinement, or simply changes in the solvent sequence or the temperature (pathway) during self-assembly can lead to the formation of kinetically trapped nanostructures. In some cases, this even enables the hierarchical organization of well-defined soft matter building blocks over several length scales.
In that respect, this issue is intended to highlight recent advances concerning all aspects of non-equilibrium block copolymer self-assembly as well as possible applications in diverse fields like, e.g., materials science, biotechnology, or supramolecular chemistry.

Title: Precise Synthesis of Block Polymers by Means of Living Anionic Polymerization

Abstract: In this review, we would like to introduce the precise synthesis of synthetically difficult diblock copolymers, triblock terpolymers, and multiblock copolymers by a sequential polymerization where two or more monomers are sequentially added to the initiator. For these syntheses, the methodology using a specially designed linking reaction in conjunction with the sequential polymerization has been developed. With this methodology, new molecular weight and structurally asymmetry triblock copolymers, A-B-A', triblock terpolymers, A-C-B, B-A-C, multiblock co- and terpolymers, A-B-C-A-B-C, and (A-B)n, have been successfully synthesized.

Abstract: We have studied the break-down of microparticles (Rh=200nm) formed by self-assembly of amphiphilic triblock copolyelectrolytes in water. The copolyelectrolytes consisted of a central hydrophilic poly(acrylic acid) block and two lateral hydrophobic poly(nbutyl acrylate-co-acrylic acid) blocks. In water the hydrophobic blocks self-assemble into microparticles consisting of several dense hydrophobic cores bridged by hydrophilic blocks. Upon dilution in buffer solutions, the microparticles break down at a rate controlled by the life time of the hydrophobic blocks within the cores. The rate of break-down was strongly pH-sensitive, rendering these microparticles potentially interesting for controlled drug release.
