methylester) microspheres were embedded into the poly (hydroxyethyl
methacrylate)(PHEMA) cryogels and the resulting composite cryogel was used for the
selective removal of cholesterol. Composite cryogels were characterized by swelling tests,
multipoint BET apparatus, SEM, FTIR and elemental analysis studies. Specific surface area
of the PHEMA cryogel was increased from 13 to 72.7 m2/g by embedding of microspheres …
