TL;DR: In this paper, a sample of triblock copolym Synperonic F127 was purified and the micellisation and gelation properties of aqueous solutions of purified and unpurified copolymers were investigated by surface tension measurement, static and dynamic light scattering, differential scanning calorimetry and NMR spectroscopy.

TL;DR: A phase diagram for aqueous solutions of oxyethylene/oxypropylene (E/B) block copolymer E41B8 is presented in this paper, where the range of techniques used (tube inversion, polarized-light microscopy, rheometry, and differential scanning calorimetry) enabled regions to be assigned to micellar sol, isotropic soft gel, and birefringent hexagonal gel.

TL;DR: In this article, small-angle neutron scattering (SANS) has been used to investigate structural changes during the de-swelling of poly(N-isopropylacrylamide) [poly(NIPAM)] microgel particles induced by temperature variation and the addition of free polymer [poly (ethylene oxide)].

TL;DR: In this article, five block copolymers with three linear architectures were prepared by sequential anionic copolymerization, i.e., E102P37, E103P34, E52P34E52, E57P46E57, and P19E113P19.

TL;DR: The phase behavior of E 40 B 10 in 0.2 mol dm -3 aqueous K 2 SO 4 was studied as a function of temperature and concentration in this article.
