Abstract: (Meth)acrylate salt polymers are prepared by free-radical polymerization of (meth)acrylate salt with or without other monomers in an aqueous medium by using a supersaturated aqueous solution of (meth)acrylate salt. The resulting highly concentrated reaction mixtures are notable for their high solids content and increased space-time yield.

Abstract: Preparation of water absorbing polymer (I) comprises polymerizing a mixture of at least one ethylenic unsaturated, acid group carrying monomer, a crosslinker and optionally a copolymerizable e.g. ethylenic unsaturated monomer and a water soluble polymer (of the monomers) to give a ground polymer (A) and treating (A) with post crosslinking agent, where before/during the polymerization, at least one water insoluble metal sulfate is added. Preparation of water absorbing polymer (I) comprises polymerizing a mixture of at least one ethylenic unsaturated, acid group carrying monomer that is partially neutralized, at least one crosslinker, optionally one or more copolymerizable ethylenic and/or allylic unsaturated monomer and optionally one or more water soluble polymer (of the monomers), which is partially grafted to give a ground polymer (A) and subsequently treating (A) with a post crosslinking agent, where before or during the polymerization, at least one water insoluble metal sulfate is added. Independent claims are also included for: (1) use of a water insoluble metal sulfate for preparing (I); (2) a water absorbing polymer particle comprising at least one monopolymerized ethylenic unsaturated, acid group containing monomer, which is partially neutralized, at least one mono polymerizable crosslinker, optionally one or more copolymerizable monopolymerized ethylenic and/or allylic unsaturated monomer, optionally one or more water soluble polymer (which is partially grafted) of the monomers, at least one reactable crosslinker and at least one monopolymerized water insoluble metal sulfate, where at least one metal sulfate is distributed in the polymer particle; and (3) a sanitary article comprising the water absorbing polymer particle.
