ABSTRACT:
A hydrophilic polymer having the water absorption capacity thereof 1 to 30 times to its own weight by a process of manufacture which comprises preparing a monomer component comprising (a) 2 to 25 mol % of a hydroxyl group-containing alpha,beta-ethylenically unsaturated monomer, (b) 5 to 30 mol % of a carboxyl group-containing alpha,beta-ethylenically unsaturated monomer, and (c) 93 to 45 mol % of a carboxylate group-containing alpha,beta-ethylenically unsaturated monomer, providing that the total of (b) and (c) is in the range of 98 to 75 mol %, radically polymerizing said monomer component, and heat-treating the resultant polymer thereby causing the hydroxyl group and carboxyl group possessed by the polymer to react with each other and form a crosslinked structure, a method for the production thereof, and uses found therefor including a cation sequestrating resin, a coolant and a coating material.
