Polyacrylamide–graft–poly(ethylene oxide)

Abstract
Water‐soluble graft copolymers were synthesized by copolymerization of acrylamide with mono‐methoxy‐poly(ethylene oxide)‐methacrylates (Me‐PEO‐MA). The Me‐PEO‐MA macromers were synthesized by a catalytic esterification of methacrylic acid with mono‐methoxy‐poly(ethylene glycol)s with different molecular weights. The graft copolymers obtained were characterized by 1H‐NMR spectroscopy, gel permeation chromatography (GPC) and Ubbelohde viscosimetry. The rheological behaviour of aqueous polymer solutions, which are expected to show hydrophobic association at elevated temperatures, was studied with a cone and plate‐rheometer.
