Abstract: Curable coating agents, a process for the production of scratch-resistant coatings on plastics, and articles coated by this process. The coating agents are polycondensates of a reaction product, containing two or more carbon-carbon double bonds and one or more hydroxyl or alkoxy groups per molecule, obtained from an olefinically unsaturated silane containing 2 or more hydroxyl or alkoxy groups, whose olefinically unsaturated organic radical is bonded via a C-Si bond, and a hydroxyl-containing alpha , beta -olefinically unsaturated monomer, an olefinically unsaturated silane of the general formula R1-Si(OR2)3 where R1 is a vinyl radical or an alkyl acrylate or alkyl methacrylate radical bonded to the Si atom via a C-Si bond and R2 is hydrogen or a saturated hydrocarbon radical, and a saturated silane of the general formula where R3 and R4 are saturated or aromatic hydrocarbon radicals, with or without an epoxide-containing silane which also contains hydroxyl or alkoxy groups; the polycondensate may additionally contain an olefinically unsaturated reaction product of acrylic or methacrylic acid and a polyalcohol or polyether-ol. The coating agent is used to produce scratch-resistant coatings on the surface of plastics.

Abstract: A process for the preparation of modified poly-N-vinylpyrrolid-2-one containing two identical reactive groups, wherein polyvinylpyrrolidone is treated with complex hydrides, with or without further reaction of the modified polyvinylpyrrolidone with a reactive bifunctional compound, to give a polymer which has a molecular weight at least 2.5 times as great as that of the starting polymer.

Abstract: Production of polymers in bead form by forming a water-in-oil suspension of an aqueous solution containing at least one water-soluble ethylenically unsaturated monomer in an inert hydrophobic liquid organic dispersion medium and polymerizing the suspended monomer in the presence of a polymerization initiator and a protective colloid obtained by reacting an oily or resinous polymer of an olefin and/or diolefin, said polymer containing hydrogen atoms in the allyl position, with 2 to 30% by weight, based on the oil and/or resin, of maleic anhydride.

Abstract: Powder coatings are prepd. by freezing a mixt. of pigment, polymer binder and solvent, removal of the solvent by sublimation under reduced press. and pulverisation of the residue. Used for application to metal substrates by sintering or electrostatic spraying processes. Powder coatings made by melt extrusion processes cannot be subsequently pigmented so colour range is limited. Removal of solvent from pigmented pastes by e.g. azeotrope distn. after H2O addn. can alter compsn. of final prod. Freeze drying avoids these difficulties.
