Abstract: Production of aqueous polymer dispersions (APD) by radical-initiated emulsion polymerisation of a mixture of : (I) radically polymerisable organo-silicon compounds which form silanols on hydrolysis with water; and (II) radically polymerisable compounds other than (I). The process comprises using at least part of (I) and at least part of (II) to make an aqueous emulsion in which the disperse phase consists mainly of droplets with a diameter of \}500 nm, then using this emulsion for polymerisation as above. Also claimed are APD obtained by this process.

Abstract: Production of aqueous polymer dispersions (I) comprises radical-initiated aqueous emulsion polymerisation of ethylenic monomers to give a dispersion of a first polymer followed by radical polymerisation of other monomers in one or more subsequent stages (i) in the presence of the first polymer, with the following features: (a) the first polymer has a Tg of Tg1, (b) the monomers polymerised in stages (i) are such that the isolated statistical copolymerisation of these monomers gives a first polymer with a Tg which approaches a limiting value of Tg1 with increasing molecular weight, (c) for each Tgi the difference Tgi - Tg1 = at least 10 deg C, (d) the amount of monomers polymerised in the first polymer is 85-99.9 wt.% of the total amount (TM) polymerised in the entire process, (e) the total amount of monomers polymerised in all stages (i) is 0.1-15 wt.% of TM, (f) in each stage (i), the addition of monomer is carried out so that monomer conversion (polymerisation) does not exceed 50 mol% of the amount already in the reactor at any time up to the end of addition, (g) apart from monomers with two conjugated double bonds, the total amount of monomer polymerised in all stages (i) contains no monomers with more than one ethylenically unsaturated group, and (h) apart from monomers with two conjugated double bonds, the total amount of monomer used for the production of the first polymer includes not more than 5 wt.% monomers with more than one unsaturated group. Also claimed are (a) dispersions (I) obtained by this process; (b) polymer powder obtained by spray drying (I); (iii) polymers obtained by this process; and (iv) aqueous dispersions containing such polymers.

Abstract: The invention relates to dispersion coloring substances with a PVK > 40 % which contain a preparation as a binding agent. The preparation comprises at least one aqueous polymerizate dispersion as component A. The polymerizate P of said dispersion comprises carbonyl groups. As component B, the preparation comprises at least one compound with at least two reactive NH2-groups opposite the carbonyl groups of the polymer of component A. The invention also relates to the application of such preparations in order to improve wet abrasion resistance.

Abstract: An aqueous composition (I) containing a copolymer (II), formed of ethylenically unsaturated monomers, as a film forming component, is used for coating mineral based molded articles. The copolymer (II) has a glass transition temperature of 25-80 degrees C and the monomer contains 0.2-5.0 wt.% itaconic acid. Independent claims are included for: (i) the production of coated, mineral molded articles by application of (I) onto at least one surface of the article and drying; and (ii) the resulting coated, molded article.
