Production of improved highly water-absorbing polymer |
| abstract |
PURPOSE: To obtain a polymer having large particle size and high absorption rate, by copolymerizing a specific polyoxyethylene glycol mono(meth)acrylate in a reversed phase suspension polymerization of an aqueous solution of acrylic acid monomer and an alkali metal acrylate monomer. n CONSTITUTION: A solution of acrylic acid monomer (preferably having a neutralization degree of 65W85mol.%) and an alkali metal acrylate monomer is subjected to reverse phase suspension polymerization in an alicyclic or aliphatic hydrocarbon solvent (e.g. cyclopentane, cyclohexane or n-pentane) in the presence of an oleophilic surfactant (preferably a sorbitan fatty acid ester having an HLB of 3W6) and a water-soluble radical polymerization initiator (e.g. potassium persulfate or benzoyl peroxide). In the above process, one or more kinds of polyoxyethylene glycol mono(meth)acrylates of formula (R is H or CH 3 ; n is 2W20) are copolymerized to obtain the objective highly water-absorbing polymer. n COPYRIGHT: (C)1988,JPO&Japio |
