The liquid chromatography of four water-soluble polymers [pullulan, polyacrylamide, poly(ethylene glycol), and poly(ethylene oxide)] have been investigated and used to categorize separation processes which couple enthalpic and entropic mechanisms. Experiments were carried out with a binary mobile ph
Poly(divinylsiloxyethylene glycol), which consists of alternating oligo(ethylene glycol)s (MW ร 300) and divinylsiloxanes were prepared by a polycondensation reaction (M n ร 6500-9300, M w /M n ร 2.01-2.27). The obtained polymer (PVSE300) showed a lower critical solution temperature (LCST) at 10.5ะC
