  • Publication number: 20150368409
    Abstract: The present invention relates to a process for the preparation of a readily water-redispersible polymer powder by spray drying of an aqueous polymer B dispersion, wherein the spray drying of the aqueous polymer B dispersion is effected in the presence of a polymer A, wherein polymer A has a glass transition temperature ?60° C., a weight average molecular weight Mw?1000 and ?25000 g/mol, a polydispersity index ?5 and is composed of ?5 and ?50 wt % of at least one ?,?-monoethylenically un-saturated mono- or dicarboxylic acid and/or anhydride (monomer A1), and ?50 and ?95 wt % of at least one other ethylenically un-saturated compound which is copolymerizable with the monomers A1 (monomer A2), in polymerized form, wherein the monomer amounts A1 and A2 sum up to 100 wt %.

  • Patent number: 8535558
    Abstract: The present invention relates to microcapsules comprising a capsule core and a capsule wall, where the capsule wall is constructed from 50 to 90% by weight of one or more C1-C24-alkyl esters of acrylic acid and/or methacrylic acid (monomers I), 10 to 50% by weight of one or more polyvinyl monomers (monomers II), and 0 to 30% by weight of one or more monounsaturated, nonionizable monomers (monomer III), which are different from the monomers I in each case based on the total weight of the monomers, to a process for their preparation, and to their use in binding construction materials, textiles and heat transfer liquids.

  • Publication number: 20090078164
    Abstract: The present invention relates to the use of epoxy derivatives which have been prepared by reacting a di-, tri- or tetraglycidyl compound (A) with an optionally unsaturated reactive component (B) consisting of a C8-C28-fatty acid, a C8-C28-alcohol or a secondary C8-C28-amine as additives to cementitious building materials. The epoxy derivatives proposed according to the invention are outstandingly suitable as compositions for preventing or suppressing efflorescence on surfaces of set cementitious building materials and/or for hydrophobing the corresponding cementitious systems. In addition, the cementitious products take up substantially less water owing to the additives proposed according to the invention, with the result that frost damage and rapid rusting of the reinforcing steel can be substantially reduced.

  • Publication number: 20070161724
    Abstract: The invention relates to copolymers based on unsaturated mono or dicarboxylic acid derivatives, oxyalkyleneglycol-alkenyl ethers, vinyl polyalkyleneglycol or ester compounds, in addition to the use thereof as additives for aqueous suspensions base don mineral or bituminous binding agents. Said invention is characterized in that the inventive copolymers, having a long lateral chain, impart small amounts of excellent processing properties to aqueous binding suspension, and simultaneously cause the water content in the concrete to be greatly reduced.
