✦ Synopsis

Polystyrene-b-poly(ethylene oxide) [P1503-SEO, M n : PS (2300) -PEO (3100), M w /M n : 1.08, PEO volume fraction: 0.56, calculated using known densities of polystyrene and poly(ethylene oxide) at room temperature (r PS = 1.05 g cm ±3 , r PEO = 1.13 g cm ±3 )

[11] Polymer Source, Inc.], liquid scintillation mixture containing 1,4bis-2-(5-phenyloxazolyl)-benzene (POPOP) and 2,5-diphenyloxazole (PPO) in toluene (Aldrich, 1 L contains 1.25 g POPOP and 100 g PPO in toluene), 6 LiOH . H 2 O (95 %), HCl (12.2 M, EM Science), toluene (Aldrich, anhydrous, 99.8 %), and methyl alcohol (MeOH, Burdick & Jackson, HPLC grade) were used as received. The liquid scintillation mixture (600 lL) was diluted (to 2500 lL) with toluene beforehand. In a typical synthesis, 40.6 mg of P1503-SEO was dissolved in 500
