TL;DR: In this paper, copolymeres bi-and trisequences forment en solution aqueuse des micelles spheriques de 2 types, which are constantes dans le domaine de concentration 2 •10 −5 −2•10 −3 g/ml.
Abstract: Des copolymeres bi- et trisequences forment en solution aqueuse des micelles spheriques de 2 types dont les dimensions respectives sont constantes dans le domaine de concentration 2•10 −5 −2•10 −3 g/ml. La fraction en masse des particules les plus grosses decroit quand la concentration augmente. Les petites particules (20 nm de rayon hydrodynamique) sont des micelles regulieres avec un nombre d'association de quelques centaines; les grosses particules (65 nm) sont des amas constitues de dizaines de micelles

TL;DR: In this paper, a general overview of block copolymer emulsion and dispersion polymerization in an aqueous and organic medium is presented for the preparation of electrosteric and sterically stabilized latex particles.
Abstract: Summary: This article deals with recent progress including the authors' work concerning the application of block copolymers as polymeric surfactants in heterophase polymerizations. The synthesis methods for preparing block copolymers by emulsion and dispersion techniques are outlined, with emphasis on recently developed controlled free radical polymerizations in aqueous media. Specific characteristics of amphiphilic block copolymers are described, for example, micellization and emulsifying effects. A general overview of emulsion and dispersion polymerization in an aqueous and organic medium with ionic and nonionic block copolymers is presented for the preparation of electrosteric and sterically stabilized latex particles. Typical examples of microemulsion, miniemulsion, oil-in-oil emulsion, and micellar polymerizations are provided. Current and potential developments of so-called “hairy latexes”, inverse-, multiple-, and solid emulsions, as well as of nonaqueous polymeric dispersions are also discussed. PS foam obtained by free radical polymerization of water-in-styrene, stabilized with a PS–PEO diblock copolymer.

TL;DR: The present tutorial review introduces the primary principles of BCP self-assembly in bulk and in solution by describing experiments, theories, accessible morphologies and morphological transitions, factors affecting the morphology, thermodynamics and kinetics, among others.
Abstract: Block copolymer (BCP) self-assembly has attracted considerable attention for many decades because it can yield ordered structures in a wide range of morphologies, including spheres, cylinders, bicontinuous structures, lamellae, vesicles, and many other complex or hierarchical assemblies. These aggregates provide potential or practical applications in many fields. The present tutorial review introduces the primary principles of BCP self-assembly in bulk and in solution, by describing experiments, theories, accessible morphologies and morphological transitions, factors affecting the morphology, thermodynamics and kinetics, among others. As one specific example at a more advanced level, BCP vesicles (polymersomes) and their potential applications are discussed in some detail.
