✦ Synopsis

Layered brucite was synthesized at room temperature and, after characterization, was reacted in a closed flask with either ethylene glycol or glycerol. Powder X-ray diffraction patterns have shown that new compounds with interlayer expansions were obtained. New bands attributed to grafting of ethylene glycol and glycerol into the interlayer surface of brucite were detected by FTIR. XPS spectroscopy and thermal analyses (TG/DSC) have shown that nearly all of the hydroxide groups of the layers were replaced by either ethylene glycol or glycerol through Mg-O-C bonds.

Zn-Al-CO 3 layered double hydroxide was synthesized at room temperature using a procedure reported elsewhere. After characterization, 0.5 g of the Zn-Al-CO 3 layered compound was reacted under air with 15 cm 3 of ethylene glycol at 80 β€’ C for a period of 5 days. ## After washing with acetone and dr

## Abstract Graft copolymers of poly(ethylene glycol) (PEG) on a chitosan backbone (PEG‐g‐chitosan) have been synthesized and their aqueous solution properties were investigated. At pH 6.5 the graft copolymers are 100% soluble, while chitosan phase separates from solution at those conditions. These
