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.

Abstract: The invention relates to novel reaction products containing urea and carboxyl groups and obtained by reacting i) a diisocyanate or polyisocyanate with ii) at least one amino compound and iii) at least one acid anhydride of an at least dibasic carboxylic acid, and optionally iv) a hydroxyl- or amino-containing compound which is different from component ii), where the total number of NCO and anhydride groups in i) and iii) is less than or equal to the number of groups reactive therewith in ii) and iv). This reaction product is suitable for the preparation of radiation-sensitive compositions, in particular compositions whose solubility in water or aqueous-alkaline solution is increased by irradiation.
