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 storage-stable solutions of film-forming copolymers containing carboxyl groups, whose carboxyl groups are reacted to 5 to 80 % with glycidyl (meth)acrylate, in an inert organic solvent or solvent mixture, these solutions additionally containing a phosphoric acid ester of a hydroxyalkyl (meth)acrylate and optionally o-phosphoric acid, and to a procedure for the manufacture of photosensitive coatings which contain photoinitiators, free-radical-polymerisable ethylenically unsaturated organic monomeric compounds, and if appropriate plasticisers, dyes, colour formers and inhibitors of thermal polymerisation, the manufacture of these coatings taking place in a storage-stable solution of this type. They are particularly suitable for the manufacture of offset printing plates.
