    Abstract: Superabsorbents are produced by polymerization in the presence of at least one unsaturated polyetherol selected from the group consisting of polyetherols having the following structural formulae (1), (2), (3) and (4): where n is 0 or 1, m is 1, 2, 3, 4, 5 or 6, o is a natural number from 1 to 200, and A is —(H2C—CHR1—O)— or —(R1HC—CH2—O)—, where R1 in each occurrence is independently hydrogen or an organic radical.

    Abstract: The use of ammonia-free, aqueous polymer dispersions (A), containing copolymer(s) (I) dispersible in the aqueous phase, is claimed as an additive for mineral building materials based on hydraulic binders, where (I) is obtained from (by weight): (a) 40-80% acrylic acid-(2-12C) alkanol ester(s); (b) 1-40% vinyl aromatic monomer(s) and/or methacrylic acid-(1-4C) alkanol ester(s); (c) 2-15% (meth)acrylic acid-2-10C alkanediol monoester(s); (d) up to 10% ethylenically unsaturated monomer(s) containing optionally salified acid group(s); (e) less than 5% ethylenically unsaturated nitrile; and (f) less than 1 wt. % alpha , beta -ethylenically unsaturated mono- or dicarboxylic acid amide. Independent claims are included for: (i) the use of polymer powder/granules (A'), obtained by removal of at least 80 wt. % of the volatiles from (A), as an additive as described above for (A); (ii) mineral building materials based on hydraulic binders containing (I), in the form of (A) or (A'), at 0.5-150% based on the dry mineral weight; and (iii) a method for improving the mechanical strength, elasticity and processibility of building materials based on hydraulic binders, involving mixing the binder(s), (A) or (A') and optionally water and/or aggregate.

    Abstract: The production of polymer powder (I) suitable for the modification of mineral binder building materials, involves drying an aqueous polymer dispersion which forms films with a Tg of not above 30 degrees C, where before drying, the dispersion is treated with drying agents (IIa) which have a liquefying action on the mineral binder when it is mixed with water and ready for use; after drying, the powder (I) is treated with finely divided solid additive(s) (IIIa) which have a solidifying action on the binder/water mix. Alternatively, the dispersion is treated with solidifying driers (IIb) before drying, and the dried powder is treated with finely divided solid additives (IIIb) which have a liquefying action on the mix. Also claimed are: (i) polymer powder (I) obtained by this process; (ii) mineral binders containing (I); and (iii) dry mortar preparations containing 20-60 wt% mineral binder, 0.1-20 wt% (I) and up to 25 wt% conventional additives, the remainder consisting of sand, fillers, pigments and natural and/or synthetic fibres.
