ABSTRACT Absorbent Polymers, Their Manufacture and Uses The properties of absorptive synthetic polymer particles formed by polymerisation of water soluble monomers such as sodium acrylate or acrylamide with a cross linking agent are improved, especially as regards absorptive capacity for aqueous electrolytes, by copolymerising the monomers with an ethylenically unsaturated monomer that includes a pendant group -AmBnApR where B is ethyleneoxy, n is at least 2, A is propyleneoxy or butyleneoxy, m and p are each less than n and are preferably zero, and R is a hydrophobic group.
