Abstract: The use of redsipersible polymer powders containing no organic emulsifier for a binder in the production of carpeting is surprisingly superior to use of the same polymers in the form of an aqueous dispersion. Tuft removal force in particular, is improved. The compositions contain no thickener, or a reduced level of thickener.

Abstract: Powder paint composition, processes for preparing and uses for the same. The composition includes (a) at least one polymer powder redispersible in water, (b) pigment and filler and (c) optionally further additives. Where (a) is a polymer stabilized with polyvinyl alcohol, based on (a1) 20 to 100% by weight of at least one monomer from the group consisting of acrylic esters of branched or unbranched alcohols having 1 to 12 carbon atoms, (a2) 0 to 60% by weight of at least one monomer from the group consisting of methacrylic esters of branched or unbranched alcohols having 1 to 12 carbon atoms and styrene, (a3) 0 to 40% by weight of at least one monomer from the group consisting of vinyl esters of branched or unbranched carboxylic acids having 2 to 12 carbon atoms, and (a4) 0 to 20% by weight of other ethylenically unsaturated comonomers copolymerizable therewith.

Abstract: Highly condensed silicon resins are obtained by a three step continuous procedure without the use of organic solvent, by preliminarily forming a partial alkoxylate by reacting a chlorosilane with alcohol containing no or a minimal amount of water, feeding the partial alkoxylate to a reaction column to form a silicone resin of low degree of condensation, and further condensing the silicone resin intermediate thus formed to produce a silicone resin product.
