Abstract: The invention concerns a process for producing water-absorbing polymer, which comprises a base polymer A being mixed with a first aqueous solution B of at least one surface postcrosslinker and a second aqueous solution C of at least one polyvalent cation and thermally treated, wherein said base polymer A is based on at least 50% neutralized acid-functional monomer and said solutions B and C are metered wholly or partly concurrently through separate nozzles whereby a water-absorbing polymer having a high saline flow conductivity value is obtained.

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.

Abstract: The present invention relates to novel mixtures of (meth)acrylic esters of polyalkoxylated trimethylolpropane of the formula where AO is for each AO independently at each instance EO, PO or BO where EO is O-CH2-CH2- PO is independently at each instance O-CH2-CH(CH3)- or O-CH(CH3)-CH2- BO is independently at each instance O-CH2-CH(CH2-CH3)- or O-CH(CH2-CH3)-CH2- p1+p2+p3 is 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74 or 75, R1, R2 and R3 are independently H or CH3, a simplified process for preparing these ester mixtures and the use of reaction mixtures thus obtainable.
