Abstract: The invention relates to the use of protective colloid-stabilized polymerizates as low profile additive (LPA), characterized in that the protective colloids carry one or more functional group selected from the group comprising carboxyl, sulfate, sulfonate, phosphate, phosphonate, hydroxyl and nitrogen-functional groups, having the stipulation that the mass fraction of the hydroxyl groups equals ?10 wt % based on the total mass of a protective colloid.

Abstract: Polyvinyl acetate polymers produced by mass polymerization or suspension polymerization are stabilized against blocking by addition of minor amounts of a silicon oxide compound during the pelletization process of mass polymerized polymers and prior to or during fluidized bed drying in the case of suspension polymerized polymers. The free flowing polymers are suitable for use as chewing gum bases, and for other uses.

Abstract: Dry jointing sand which is swept into joints is consolidated by addition of a powder composition employing either a polyvinyl alcohol-stabilized redispersible polymer powder which contains functional post-crosslinking comonomers, or a redispersible polymer powder stabilized by a polymer of one or more ethylenically unsaturated mono- or dicarboxylic acids and/or anhydrides thereof. The sand is bonded within the joints upon contact with moisture.

Abstract: BMC molding compositions containing carboxy-functional polyvinyl acetate resins having minimally 3 weight percent of carboxy-functional monomers exhibit only modest increase in viscosity upon addition of fillers as compared to similar compositions employing polyvinyl acetate homopolymers.

Abstract: Polyvinyl acetals prepared by acetalizing a hydrolyzed polyvinyl acetate homo- or copolymer with at least one of formaldehyde, acetaldehyde, propionaldehyde, or butyraldehyde are low profile additives in unsaturated polyester molding resins which still provide a uniform pigment distribution in molded parts.

Abstract: Paintability of articles prepared by molding of an unsaturated polyester moulding composition is enhanced by replacing a portion of low-profile additives contained in the composition with solid polyvinyl acetate copolymer(s) containing from 3 to 10 weight percent of monoethylenically unsaturated organic carboxylic acid monomer units.

Abstract: A process for recycling of powder coating waste comprising the steps of (1) compressing powder coating waste to powder coating compacts having a volume of 0.5 mm3 to 15 cm3 by applying pressing forces; (2) placing the formed powder coating compacts into a vessel, rotating the vessel about a rotational axis inclined at an angle of 20 to 70 degrees relative to the horizontal and (3) heating the powder coating compacts while being moved in the rotating vessel until through-glassed powder coating bodies are formed.

Abstract: Process for recycling of powder coating waste, wherein powder coating waste is moved in a vessel rotating about a rotational axis inclined at an angle of 20 to 70 degrees to the horizontal and is thereby exposed to heat, until powder coating agglomerates with a size of 1 mm to 3 cm or 1 to 10 mm or powder coating pearls with a size of 1 to 10 mm are formed.

Abstract: Pulverulent compositions for binding particulates, comprise A) 10 to 99.99 parts of at least one pulverulent interpolymer having a glass transition temperature Tg or a melting temperature of ≧30° C. and containing units derived from a1) comonomer(s) of vinyl esters of optionally branched C1-18 alkylcarboxylic acids, (meth)acrylic esters of optionally branched C1-15 alcohols, dienes, olefins, vinyl aromatics or vinyl halides, and a2) from 0.1 to 50% by weight, based on the total comonomer weight, of ethylenically unsaturated functional comonomers; B) 0 to 89.99 parts by weight of a pulverulent compound which bears two or more functional groups capable of reacting with functional groups of interpolymer A); and C) 0.01 to 90 parts by weight of a melt viscosity depressant having a glass transition temperature Tg or a melting temperature of ≦150° C.

Abstract: A process for the recycling of polymeric powder coating waste involves the steps of contacting polymeric powder coating chips with the powder coating waste to form a combination, by applying the powder coating waste to at least a portion of the surface of the powder coating chips, followed by heating the combination to a temperature and for a period of time sufficient to firmly bond the powder coating waste to the powder coating chips.
