Phase behaviour and structure of amphiphilic poly(ethylene oxide)-poly(propylene oxide) triblock copolymers ((EO)(4)(PO)(59)(EO)(4) and (EO)(17)(PO)(59)(EO)(17)) in ternary mixtures with water and xylene
The isothermal ternary phase behaviour and structure of amphiphilic copolymer-water-xylene systems was investigated for two poly(ethylene oxide)-poly(propylene oxide) (PEO-PPO) triblo k copolymers, (EO)(4)(PO)(59)(EO)(4) and (EO)(17)(PO)(59)(EO)(17), at 25degreesC. The phase boundaries were identified using H-2 NMR and inspection under polarized light. The microstructure and structural length scal
