Abstract: The acrylic acid alkali metal salt polymer is prepd. by dispersion suspending a high concn. monomer soln. of at least 40 wt.% acrylic acid and acrylic acid alkali metal salt in the alicyclic hydrocarbon solvent contg. surfactants of 3-6 HLB and 8- 15 HLB, polymerizing and crossliking the suspension in the water-soluble radical polymn. initiator by the reverse suspension polymn., and adding silica or cellulose fiber to the crosslinked polymer. The polymer is granul type having regular particle size, and has a good absorption- and water holding- capacity.
