A number of results reported on the kinetics of exchange of triblock copolymers poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide), PEO-PPO-PEO, between micelles and the intermicellar aqueous solution are reviewed and analyzed to extract the rate constants k(+) for the entry of a copoly
Measurements have been made to determine the solubilities of three hydrocarbon gases, methane, ethane, and propane, in aqueous solutions of four different water-soluble triblock copolymers of the Pluronic class: Pluronic P103, P104, P105, and F108. The solubilities of each gas, measured at 25 • C, f
## Abstract Polystyrene latexes were produced via a newly accessible miniemulsion polymerization where reactive poly(ethylene oxide)–poly(propylene oxide) –poly(ethylene oxide) triblock macrosurfactants were used to impart the interfacial activity during the emulsification and the reactivity in the
